I searched all the archives, but I don't assure to have checked so deep :)
so far I found a longer explanation by u, but u couldn't give details on how
to modify spec file in that post

I have installed the rpm kernel source
http://ccrma-www.stanford.edu/planetccrma/software/recompilekernel.html
from this link, that put files in /usr/src/redhat

moreover also the binary source (from core cd), that put files in
/usr/src/linux-2.4.21.1-ll-acpi,
where I tried to make the first attempts of recompiling...before discovering
that I had to do in a different way

 If you get errors please let me know, the source rpm rebuilds

I will post u the output of any encountered problem during the rebuilding,

hmmm, make sure you have disabled

I will look surely at the suggestion u made

I don't know, since I didn't still searched, anyway the modem is a Bewan usb
adsl st compatible,
and specifically for mdk9.1 or linux kernels 2.4.21-x needs those patches
added, since without, after doing a modprobe unicorn_usb, the modem turns
on, but I get (as specified from the modem drivers documentation) a system
freeze, and at the reboot a kernel panic after the usb checkin, telling me
problems with interrupts and somthin else I can't remember...after
unplugging the usb cable, all works fine...
but I'm trying to make work all :)

so from my not so documentated point of view these two patches r not kernel
specific, but modem specific, who work on kernel for being implemented.....

but probably u mean that I have to install kernel 2.4-22......so another
question rise...

do I have to uninstall the kernel rpm of 2.4.-21-1.ll.acpi? (doing rpm -e
.....)
