Over the weekend, I was able to test this patch using all my b43 hardware. There
were no problems.

Despite having no problems, I still NACK the patch for the reason that b43 only
applies to devices with id.revision >= 5, thus the revised "if" will always be
true. The patch should be rewritten as only b43legacy needs to test the 802.11
core revision.
