No, it's a bog-standard old-fashioned BIOS.  There is a toggle in
there for the wireless, but it doesn't seem to do anything.

Yes, this might be useful:

That's interesting - is it usual to have $(VENDOR)-wireless and
phy$(IF_NUM)?  I don't have an equivalent toshiba-wireless, but the
EeePC does have eeepc-wlan.

I don't recognise the page, but I do recognise the suggestions:

jtait at mothership:~$ sudo iwconfig wlan2 power off
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan2 ; Operation not supported.
jtait at mothership:~$ sudo modprobe -r iwl4965
jtait at mothership:~$ sudo modprobe iwl4965 11n_disable=1
jtait at mothership:~$ rfkill list
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

Something seems to be missing at a fairly low level.  I install
laptop-mode-tools on the off-chance it would pull in some magical fix,
but it didn't.  I'll give 13.04 a crack, as soon as I have media
available to boot from. :)

Thanks for all the suggestions so far!
