i don't think the problem is your south bridge. very few
of them need to be recognized, so they aren't. the problem
is likely that you need the vid/did of the ide controller in
your motherboard added to the ata driver. if you have
a system on which you can compile a kernel, try applying
this diff
; diffy -c /sys/src/9/pc/sdata.c
/n/dump/2008/0229/sys/src/9/pc/sdata.c:1960,1965 - /sys/src/9/pc/sdata.c:1960,1968
r = pcicfgr8(p, 0x46);
pcicfgw8(p, 0x46, (r & 0x0C)|0xF0);
/*FALLTHROUGH*/
+ case (0x7401<<16)|0x1022: /* AMD 755 Cobra */
+ case (0x7409<<16)|0x1022: /* AMD 756 Viper */
+ case (0x7410<<16)|0x1022: /* AMD 766 Viper Plus */
case (0x7469<<16)|0x1022: /* AMD 3111 */
/*
* This can probably be lumped in with the 768 above.
if you don't contact me offline and we'll figure something out.
