I've tested with 2 others pcmcia nics: (on my T43)
-Atheros based (module ath_pci)
Doesn't have /sys/class/net/ath0/wireless
-Ralink 2500 based (module rt2500)
Has /sys/class/net/ra0/wireless, but kernel warns this is deprecated
"ra0 (WE) Driver using old /proc/net/wireless support, please fix driver !"

It looks like a kernel driver level problem ?
