I managed to build a working kernel for ATI’s SB600 chipset under gentoo 2007.0 hardened. I tried to use =sys-kernel/gentoo-sources-2.6.23-r3 but the bloody thing wouldn’t boot. So I emerged =sys-kernel/vanilla-sources-2.6.24_rc7 and everything worked just fine.
Here I read that there are two problems with this chipset, one hardware-relevant (thank you, ATI) and a kernel-bug. The latter one has been fixed in 2.6.22-rc2. Nevertheless, =sys-kernel/gentoo-sources-2.6.23-r3 seemed not to work.
I attached my config.gz. Below, you’ll find what lspci found.
