[CentOS] Kernel Panic with wl.ko (Broadcom wireless driver) [CentOS 5.4]

Been experimenting with CentOS 5.4 some more. In order to get my wireless
card to work (Broadcom BCM4311) I need Broadcom's wl.ko driver (http://
www.broadcom.com/support/802.11/linux_sta.php). It compiles fine after
the necessary modification in typedef.h, loads and wireless works.
However, as soon as I put some load on that interface (scp something from
another machine, download something with Firefox, etc.) the machine
kernel panics. I've tried the stock 2.6.18 kernel, the latest
2.6.18-164-11, and the latest patched 2.6.18-164-11-bug4139.4192.4196
(necessary to get my ALPS touchpad to work). I've tried two different
versions of Broadcom's driver: 22.214.171.124 and 126.96.36.199. It doesn't
kernel panic when I unload the wl kernel module, plug in a network cable
and copy those files over ethernet.
I downloaded the 2.6.27 kernel source and compiled my own kernel and it
seems to work with that. However, for some weird reason, with any given
self-compiled kernel (tried 2.6.18-8, 2.6.25 and 2.6.27) klaptop won't
allow me to configure any standby/hibernation options because it doesn't
recognize any of them. They do work perfectly fine though, I can pm-
suspend the laptop from command-line.
Any idea what else I could do? Either getting wl.ko to work with 2.6.18
(does somebody have a version older than 188.8.131.52 that they could email
me?) or getting klaptop to realize that the laptop does indeed know how
th suspend and hibernate with a non-CentOS-kernel would be fine.
