I go to tldp.org down laod sound howto, I did not see ac97 is supported chip
"AC'97" is a generic name and refers to several audio chipsets. What you're more interested in is this line:
00:1f.5 Multimedia audio controller: Intel Corp.: Unknown device 24c5 (rev 02)
and its reference to 24c5. Doing a quick google for "24c5 linux" leads me to suspect that this particular variant of the AC'97 is not yet supported by the standard kernel drivers. I suspect that it _will_ be supported, but not yet. You might want to go the ALSA route or put in a cheapie supported soundcard in the meanwhile.
As to your network problems, you have two ethernet cards/circuits, as indicated by:
02:05.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 24) 
02:08.0 Ethernet controller: Intel Corp.: Unknown device 1039 (rev 82)
Again, the onboard controller looks like it might be unsupported. I'd recommend using the 3com (it's a good card). Just use "modconf" to add the 3c905 driver (and make sure that's the ethernet port you've got your ethernet cable plugged into). You might also want to turn off the on-board ethernet controller in the BIOS.
