> ... Windows driver, you could try another one ...
I've tried these two drivers: 
ftp://ftp.support.acer-euro.com/notebook/aspire_1360/driver/80211g.zip
ftp://ftp.support.acer-euro.com/notebook/TravelMate_4000_4500/driver/a802.zip

they both work with old driver, but no with the new.
I've tried to use no preempt kernel, but the same, works only the old driver.

I've compiled ndiswrapper with DEBUG=3 in such way (self made):

# mkdir /usr/local/portage/net-wireless/
# cp -a /usr/portage/net-wireless/ndiswrapper /usr/local/portage
# mkdir /var/tmp/portage/ndiswrapper-1.0_rc4
# ebuild
# /usr/local/portage/net-wireless/ndiswrapper/ndiswrapper-1.0_rc4.ebuild
# unpack
#cd /var/tmp/portage/ndiswrapper-1.0_rc4/work/ndiswrapper-1.0rc4/
# make DEBUG=3
# ebuild
# /usr/local/portage/net-wireless/ndiswrapper/ndiswrapper-1.0_rc4.ebuild
# install
# ebuild
# /usr/local/portage/net-wireless/ndiswrapper/ndiswrapper-1.0_rc4.ebuild
# qmerge

That's output from logs:
