Problems with fxp0 and wi0 devices

I'm running FreeBSD 5.2.1-RELEASE on a ThinkPad T23 and I can't use either
of the built-in fxp0 or wi0 network adapters.

Whenever I try and configure them with dhclient, dhclient just hangs.
Whenever I try and configure them manually (static IP and route), packets
never go anywhere.
Whenever I access fxp0, I get "fxp0: device timeout" messages on my screen.

I looked through cvsweb and didn't see anything that looked useful post
5.2.1-REL.

Here is the relevant part of dmesg:

fxp0: <Intel 82801CAM (ICH3) Pro/100 VE Ethernet> port 0x7000-0x703f mem
0xc0200000-0xc0200fff irq 11 at device 8.0 on pci2
fxp0: Ethernet address 00:d0:59:33:b2:eb

wi0: <Intersil Prims2.5> mem 0xec000000-0xec000fff irq 11 at device 2.0 on
pci2
wi0: 802.11 address: 00:20:e0:89:4e:0c

wi0: Intersil Firmware: Primary (1.0.5), Station (1.3.3)
wi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

And pciconf -l:
