My Sager NP4760 laptop:
Chipset: SiS M650/962
ATI Radeon Mobility 9000
PhoenixBIOS

There are major problems between linux kernels and this laptop. The newest version of Mandrake's kernel that will load is 2.4-8, THAT'S MDK 8.1!!!
2.4.22 black screen when kernel loads (like right after you push enter when the CD boots)
2.4.21 same thing with the exception of Severn (Redhat beta)
2.4.20 this works. CoolLinux, SuSE8.2, Slackware 9.0, and every other distro/version with a 2.4.20 kernel with 1 exception, and I forget what that exception is
2.4.19 doesn't work, black screen thing where system just dies

KNOPPIX 3.1-3.3 will not work however MEPIS works perfectly, including my Orinoco WLAN card, and is totally awesome. I'm currently using SuSE 8.2 and I don't really like it
