Didn't know about lspci; thanks.
If I'm reading the output correctly, though, I'm not using a VIA IDE
interface:
[nanny-ogg:~/mail/.spools]$ lspci
00:00.0 Host bridge: Advanced Micro Devices [AMD]: Unknown device 700c (rev 11)
00:01.0 PCI bridge: Advanced Micro Devices [AMD]: Unknown device 700d
...
00:07.1 IDE interface: Advanced Micro Devices [AMD]: Unknown device 7441 (rev 04)
00:07.3 Bridge: Advanced Micro Devices [AMD]: Unknown device 7443 (rev 03)
00:08.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev 01)
The computer did come with a PCI IDE controller card (the "unknown mass
storage controller" line above) that has another two controllers on it.
I haven't yet tried switching controllers to see if that helps at all; I
may attempt that later this afternoon.
Alternatively, should the fact that lspci keeps saying "unknown device"
worry me?
