Bug#345647: madwifi driver causes kernel oops

Package: madwifi-source
Version: 20051111
I've built the module against the Debian "official" kernel
2.6.14-2-686 (version 2.6.14-7).
I have a ThinkPad A22p and an Enterasys Networks PCMCIA a/b/g card. I
will attach the output of "lspci -vvv".
When I click "scan for networks" in kwifimanager, kwifimanager
crashes, and dmesg shows this:
Unable to handle kernel paging request at virtual address 0000ffff
printing eip:
e0aa9fff
*pde = 00000000
