Just a confirmation that I ran into this issue also after installing the new xserver-xorg 6.9 kits on my Ultra60 with an Elite3D/M3 card. The suggested workaround (putting cfb and cfb32 in the xorg.conf modules list) worked for me.
Luckily I didn't get around to installing this stuff until today so I could find the bug report in Google!
Thanks Christopher,
