I have applied your 4 patches on both a vanilla 2.6.21.5 kernel and
a 2.6.22-rc6 wireless-dev one, and i found that only patches 1/4 and 2/4 are
good.
the 3/4 one gives this bogus output:

airo(): Probing for PCI adapters
PCI: Setting latency timer of device 0000:05:08.0 to 64
airo(eth%d): cmd:111 status:7f11 rsp0:2 rsp1:0 rsp2:0
airo(eth%d): Doing fast bap_reads
airo(): WPA is supported.
airo(eth0): MAC enabled 0:d:29:4f:c:be
airo(): Finished probing for PCI adapters

and the 4/4 definitely broke all:

airo(): Probing for PCI adapters
PCI: Setting latency timer of device 0000:05:08.0 to 64
airo(eth%d): cmd:111 status:7f11 rsp0:2 rsp1:0 rsp2:0
airo(eth%d): Doing fast bap_reads
airo(eth%d): Bad MAC enable reason = 2, rid = 0, offset = 0
airo(eth%d): MAC could not be enabled
airo(): Finished probing for PCI adapters
