Wow. You've been busy. :) Glad you got it working. For what it's worth,
what WAS your component ID?

I'm running this:

wi0: <Intersil Prism2.5> mem 0xf0000000-0xf0000fff irq 9 at device 2.0 on pci2
wi0: 802.11 address: 00:20:e0:8a:90:61
wi0: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI)
wi0: Intersil Firmware: Primary (1.1.1), Station (1.7.4)
wi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

And it's very stable even with 104 (128) bit WEP encryption in infrastructure
mode (haven't tried hostAP or ad-hoc). I think I'll probably continue running
WEP once I get my IPSec stuff setup. Nothing like multiple layers to deter
intruders.

Well, if you were experiencing that in Windows XP too, then I'd say it's a
firmware issue.
