> What does lspci say about the host/pci bridge ?

I'm not quite sure what you were asking for.

I first did an lspci -t, knowing that my video card was 01:00.0, and
found the following line (coming off bus 00):
+-01.0-[01]----00.0

So it looks like 00:01.0 is the AGP bridge. I looked in there with lspci
-v -v -s:
joshua@shebang:~$ sudo lspci -v -v -s 00:01.0
0000:00:01.0 PCI bridge: Intel Corp. 82855PM Processor to AGP Controller
(rev 03) (prog-if 00 [Normal decode])
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR+ FastB2B-
Status: Cap- 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Latency: 96
Bus: primary=00, secondary=01, subordinate=01, sec-latency=64
Memory behind bridge: d8000000-dfffffff
Prefetchable memory behind bridge: e8000000-f7ffffff
BridgeCtl: Parity- SERR- NoISA+ VGA+ MAbort- >Reset- FastB2B-

So there's my AGP bridge: part of the 82855PM.

For good measure, I'll also give you the lspci details about the
graphics card:
