Subject: [PATCH V2] bcm43xx: Fix failure to deliver PCI-E interrupts

The PCI-E modifications to bcm43xx do not set up the interrupt vector
correctly. Tested with BCM4311 (PCI-E) on x86_64 and BCM4306 (PCI) on i386.

John,

This fix should be applied to wireless-2.6 _AND_ pushed upstream to
2.6.20-rcX. Without this patch, none of the PCI-E interfaces will work.
This version incorporates Michael Buesch's comments, and forgoes some
code clean-ups that were in the first version/

Larry
