As this is a hardware-specific problem, it doesn't fit the normal
RC-severity requirements for the kernel packages.  FWIW, I've had problems
with bcm43xx on i386 as well, which I think are attributable to the youth of
the driver.  I'm assuming you don't actually think it's a good idea to
*disable* the bcm43xx driver in the kernel packages to avoid shipping with
this bug, so that would make it an important bug that we should try to fix,
rather than an RC bug that must be fixed before release.

Thanks,
