ndisgen failure to compile stub module

Hello,

I'm trying to get the built in wireless (broadcom) working on my new laptop 
with ndisgen, but I get an error during the last step. The laptop is an HP 
ze2000 (turion64) and I've tried this using the amd64 versions of 5-STABLE 
and 6-Beta3.

The error message is as follows:

Press enter to compile the stub module and generate the driver
module now:

Compiling stub... done.
Linking loadable kernel module... /usr/bin/ld: windrv_stub.o: relocation
R_X86_64_32S can not be used when making a shared object; recompile with 
-fPIC
windrv_stub.o: could not read symbols: Bad value
linking failed. Exiting.

The drivers I've been using are here:
ftp://ftp.support.acer-euro.com/notebook/ferrari_4000/driver/winxp64bit/80211g.zip

(These match the pciconf information for the card and work in Gentoo with 
ndiswrapper)

pciconf -lv gives: 
none5_at_pci5:2:0: class=0x028000 card=0x1355103c chip=0x431814e4 rev=0x02 
hdr=0x00
vendor = 'Broadcom Corporation'
class = network


Please let me know if you need any more information.

Thank you,
Ian Larsen
