cxm WinTV PVR-250/350 driver

[Vincent Stemen]

Hey Sascha.

We finally booted our TV server on HEAD with that cxm driver patch.
Tried loading the cxm modules.  Here are the errors.

 # kldload cxm
 link_elf: symbol iicbus_start undefined
 kldload: can't load cxm: Exec format error

 # kldload cxm_iic
 link_elf: symbol iicbb_callback_desc undefined
 kldload: can't load cxm_iic.ko: Exec format error

At least the system didn't crash :-).
This machine has two TV cards.
