Similar problem for me. After updating to the 2.6.32-33-generic-pae kernel my
intel wireless stopped working. dmesg shows:
[ 15.261265] iwlagn 0000:03:00.0: firmware: requesting iwlwifi-5000-5.ucode
[ 15.454997] iwlagn 0000:03:00.0: Driver unable to support your firmware API.
Driver supports v5, firmware is v0.
[ 15.455008] iwlagn 0000:03:00.0: Could not read microcode: -22

[ 15.953192] iwlagn 0000:03:00.0: Driver unable to support your firmware API.
Driver supports v5, firmware is v0.
[ 15.953208] iwlagn 0000:03:00.0: Could not read microcode: -22
I tried this with both 1.34.7 and 1.34.10 of linux-firmware but it did
not help. Rebooting back into the older 2.6.32-32 kernel solved the
issue for me
