I overlooked the obvious:
The only 2 distros working on my X10 are
Red Hat 9.0
Knoppix 3.2 (HDD install)
Both of these work perfectly with the default driver (nv for RH 9, can't remember which one for Knoppix 3.2).
None of the following installed properly (let alone worked):
SuSE 8.1 Pro
Lycoris Build 46
Gentoo 1.4 (stage3)
LinEx 3.0 r1 (Debian Woody)
Why don't you give RH 9 a try?.
Everything graphical works OK.
