I've never had any problem with IRQ sharing under Win 98 or ME.

Windows XP is especially good at sharing IRQs.  That alone is
reason enough to upgrade, IMO.  I've been using it for about a
year now with all kinds of programs and hardware and never a
conflict.  I didn't have to set any IRQs myself - WinXP handled
it all.
