I see a few problems here:

This commit seems to depend on some commits prior to it, as it touches
drivers/net/wireless/b43/wa.c which is absent in 2.6.24.3. When I get home,
I'll test if it still works if you ignore wa.c

The patch may be too complex for -stable. I think there was a hard line
count limit, like no more than 100 lines. I'm not sure if this still stands.

This does not fix the bcm43xx driver.
