Since commit 85a83d26697dd2203ac4e5f33022951f2c3e6e33, "bcm43xx-mac80211:
Rewrite and simplify handling of the initialization status", some PCI
adapters have problems due to interrupts happening before the device status
reaches BCM43xx_STARTED. This patch delays the initial interrupt enable until
after the device status is set.

John,

This patch fixes a regression since 2.6.23-rc1. Michael and I have discussed this
and he has agreed that this is the proper fix.
