"Soonish" being rather earlier than 20071227?
'cause it's still throwing a fit for me on 2.6.24-rc6-mm1(!) (plus hotfix),
nothing visible in /proc/bus/usb, thus WLAN driver won't probe
anything.
Side note: later upgraded from hotplug-based setup to udev,
but didn't change status quo of problem of empty mount.
Now back again to a 2.6.19ish kernel, since this is the only one
that I could always fall back on after a sizeable number of attempts
to get to run anything newer trouble-free in this environment.
Frankly I'm slightly getting fed up with the number of regressions
I'm hitting in my smallish environment lately. But that's sorta
what you pay for when going experimental.
Just the same day I also had to discover that e100 doesn't usefully
support (IOW, fatal resource probing error) my Intel BNC combo 645477-004,
as opposed to eepro100. Swapped the card from this ""production""
headless box to an easily accessible one for followup debugging of e100.
