SegFault loading hostap_plx 0.1.0 (CVS of 10/11 does too)

i get the following in dmesg when trying to load 0.1.0 driver cross compiled on SuSE 8.0 stock gcc.

the source is 2.4.20 for Wisp-Dist 2625.  it compiles fine as does CVS of 10/11.  the segfault locks the card, but doesnt lock the computer or its routing functions...  Im not entirely convinced that it has anything to do with the hostap driver, but was hoping that someone might make something of the following dump the computer took...
