I have a 486 with an Avance card that uses this chip, and it had the same
problem. The garbage that you see is actually a translation, something
like abcdefgh -> bcdefg0h, so you can actually "read" it. The workaround
I used was to leave at least one VC logged in and type "setfont default8x16"
whenever I needed a VC, and the same when quitting X.
I never found any documentation for memory exclusion, but perhaps it's in
the X sources. I now use the machine as a laboratory winlose playground.
