I just found this, which would indicate that only the DOS models can go to
196 MB (4 on-board + 64 SIMM + 128 SIMM):

of course, they want you to buy their parts and only their parts which are really high priced too !! actually I think a lot of people quoting each other and the entropy effects in that are less information. the reference above i gave the guy actually describes doing real tests. of course the proof is if it works or not. one thing i know is that my 16MB single sided cards do not work in either of my quadras. though they work in the performa450/lcIII/68030. so i suspect though i am not sure that they should work in the second slots of the 631. and/or most likely if the 610/650 have a second slot. why the 631 is different from those ?? when i studied the apple ram guide though i thought that the DOS 630 was actually had a 486 motherboard in the case with the mac and that took another 32MB card originally. what do you have now. do you have any double / single sideds that you can switch around just to test that part of the theory (that slot 1 is double sided and slot 2 is single).
(They also claim their hugely expensive 128 MB SIMM works in the Q605, as Michael said.)
but the one i got is not theirs it is simply a performa6100 128 that a mac-place near here says works in quadras. it is still pricy though compared to modern memory that sells 500mB for $50. also I think it is not supposed to work in anything other than 630/605/475. the big simms were supposed to work in any quadra, although they are xtra wide and you might not be able to close the case cover on a 610 say.

It works !! more or less. I took 5 minutes to start the first time, i was just sitting there dozing. it took a long time the first time to start the window manager even longer than the server. problems : 1) it refuses to believe i have more than 300k of video ram. I know i have at least 640x480x2 bytes, upward of 512k... but it will only go in 640x480x1 Byte not 640x480x2 or 800x600x1 as in macos. 2) most apps that have both X and console versions won't start their X versions. for instance xemacs -nw works but not xemacs, info and w3m produce their text versions in the window you type but do not start from the menu (on ppc both ways give you new windows). but graphicsmajick xedit xman all work so i don't know what's up. 3) the cursor keys don't work in X. it could be a memory problem. i was running xemacs in an xterm and loading html rendering hypertext with w3m mode and it was only swapping moderately (about 10MB).

Was this a regression in linux 2.6 on your Q605/sarge box? Or does neither the 2.2 nor 2.6 kernel support 1 bpp or 4 bpp fbdev (on either mac)?
I have not tried Xfree on 68k (on Sarge) and am now Xorg stuck with 2.6. (but I tested 1bit video with Xfree4.4 on netbsd68k november2006 release) Anyway looks like its the fbdev driver in/with xorg that does not support below 8bit color. or else the fbdevhw thing that it calls, i don't know all i know is i tried it and X told me " ... not supported ".
