Ach so! Thank you very much for clearing up this little item that was
bothering me. I did experience loss of the ndiswrapper - Broadcom XP
wireless driver when I went from the generic 2.6.12 kernel to the 2.6.14
kernel specific to the amd64-k8. Then the kernel moved to the 2.6.15
series and I was in the 2.6.15-1 version -3 before I got the wireless
working again. I _did_ have to recompile the ndiswrapper which had gone
from version 1.7 to 1.8 in the meantime and apparently is only available
as source in the Debian distribution. Then I noticed, after the update
to version -4 of the kernel, I did _not_ have to recompile ndiswrapper.
The wireless just kept working! Great!
Thanks again. fgd.
