I'm afraid you're in the same boat as myself with the HUAWEI phone drivers (I have an earlier thread on this).
The
sys files in the Nokia driver package are all directly dependant on
ntoskrnl.exe (and other XP-only files) and the
dlls are mostly missing functions in
setupapi.dll,
kernel32.dll and others.
I'd say they did their best to make sure Win9x is out of question.
