6.0-BETA4: pci/vfs panic

I was trying to get a U10 configured to use wireless, but got the
following panic after I inserted an 11b card into the PCI-PCMCIA
adapter; the card first fails to attach, then any filesystem
access triggers the panic:

Before the panic, the wireless card fails to attach, with:

wi0: <MELCO WLI-PCM-L11> at port 0x100-0x13f irq 2000 function 0
config 1 on pccard0
wi0: record read mismatch, rid=fc01, got=1fc
wi0: record read mismatch, rid=fc01, got=1fc
wi0: mac read failed 5
device_attach: wi0 attach returned 5

The full serial console log can be found at

at http://www.cran.org.uk/bruce/crash/20051009_6beta4_vmcore.0.gz.

Do wireless cards work on sparc64, or are they generally only supported
on x86?
