Oh? I'm using linux-wlan-ng, I pretty much just compiled and installed
it. I was happy to use the orinoco_pci driver until I discovered that
it completely hoses things if you send a lot of data. I can send at
full tilt for a second or three, and then it loses its interrupts, or
something, and just stops working.

I tried linux-wlan-ng instead. It's worked perfectly for me in the
past, and my only gripe is that it does not support the wireless
extensions, which means you have to do a lot of manual work to
configure it to work in a multi-network environment. (I use three or
four different networks, some with WEP, some without.)

Ah! So you have that problem too! I'd appreciate it if you'd leave a
comment to that effect in the Fedora bugzilla system. This is bug
#112674 in their tracking system:

I hope you have hibernation working first, though. ;-)

Weird!

Nope, never looked at that.

Functionally, perhaps, but I never liked the layout of it. It's also a
bit thicker (0.81" vs 0.75") than the T23. I just checked those
measurements, I'd have sworn the difference was bigger.
