I recently got a mini-pci card out of an old/dead Netgear router,
and would like to add support for it in drivers/net/wireless/mwl8k.c
Ive hacked the PCI-ID into the driver

but this only gets me an error loading firmware.
Ive been unable to locate any firmware so far.
I did pull the GPL tarball from netgear; its a 2.4.27
kernel, with 1 firmware mentioned in the -readme:
[jimc@groucho marvell_WNR854T]$ grep 11 WNR854T_README.txt
This package contains Marvell 11n-draft wireless driver v.2.1.11.p0
but the apparently mentioned file is an ARM executable,
which is quite different from the firmwares that the driver uses.
[jimc@groucho marvell_WNR854T]$ file romfs.src/etc/ap8x-2.1.11.p0.o
romfs.src/etc/ap8x-2.1.11.p0.o: ELF 32-bit LSB relocatable, ARM,

Could someone explain that arm object to me ?
Does this wifi chip have an ARM core in it, and this is the "firmware" ?
fwiw, I get errors when trying to read those dbase 3 files:
[jimc@groucho netgear]$ dumprecs helper_8366.fw
Could not open file helper_8366.fw

Ive signed up to Marvell extra-net, but havent heard back
re NDA, or any of the technical info I would need.
