2.6.12-6 and xorg

[Cedric Pradalier <cedric.pradalier@inrialpes.fr>]

Hi,

I'm using testing, and I am on the verge to updation my
ibook (G3, rev 2.2). I've just found out a quite massive
change (300M+ to download). So I'd like to have some advice
before...

For the kernel, the essential for me are 
- sleep (with PMU), 
- sound,
- pppoe + firewall 
Any success?

I've also found that xorg is replacing x11. My old xserver
was tuned so as allow multiple displays (mergedfb,
xinerama). Does anyone has some success story with that on
xorg. I would not update otherwise. 

I'm seldomly using 3D, but what about DRI?

Thanks for your hints.
