I applied isdn-2.6.2-rc2.diff.gz to 2.6.3-rc1 (actually to BK as of
about Friday). Works fine for dialup, including isdn_lzscomp, on SMP.

Dies horribly upon an incoming v.110 call though...

(akpm/linus please note v.110 is fairly esoteric and it won't even
_compile_ in 2.6 at the moment so this is not a reason not to merge
Karsten's patch, which does at least make ISDN usable again in 2.6)
