With hw.cbb.start_memory=0x520000, none of my wireless cards work; they
all report "Expecting link target, got ..." With it set to 0x88000000,
my Atheros based card works, but my other two don't.
The Atheros reports
Oct 25 21:14:13 laptop kernel: cardbus1: Non-prefetchable memory at 88000000-8800ffff
Oct 25 21:14:13 laptop kernel: ath0: <Atheros 5212> mem 0x88000000-0x8800ffff irq 11 at device 0.0 on cardbus1
(and ath0 then works)
The ADMtek one reports
