Pavilion L2005cu XPRESS 200M Works
Pavilion zv6000 XPRESS 200M 5955 Works Driver 8.24.8 is known to work, 8.25.18 and 8.26.18 are broken. You have to enable Sideport UMA and assign 128MB of memory as the chipset always reports it is equipped with 256MB no matter what you configure it to.

Compaq nx8220 Ati X600 Works
HP nw8240 FireGL v5000 Works* Tested under SuSE Factory with xorg 7.2, fglrx module/driver v8.35.5 patched to build with kernel 2.6.20 -- still can't get suspend-to-ram (s3) to work properly. OpenGL acceleration works fine at 1920x1600px but Google Earth caused a system hang, which I'll try to fix using fglrx v8.36 and changing settings with Catalyst.
HP nc6400 Ati X1300 Works Gentoo Tested under xorg 7.1 with xgl/beryl
HP nc8230 Radeon Mobility X600 Works Debian/GNU unstable Tested under Debian/GNU unstable under xorg 7.2-5, kernel 2.6.18-3-686-bigmem and running the ATI-supplied installation package v8.38.6. Works fine, haven't verified TV-out et al, but running dual x-servers (dual-head with diffrent resolutions) works fine.
