I see several things that should be fixed in ISAPNP.  I'm working
on those, but they're probably post-2.6.27 material.

In the meantime, are you seeing new problems that were introduced
between 2.6.26 and 2.6.27-rc3?  If so, I should try to fix them
right away so we can get a fix in 2.6.27.

Your original report of "WARNING: at lib/vsprintf.c:609 vsnprintf+0x36/0x43d()"
has been fixed already.  I *think* the remaining issues about the
parport1 IRQ and the MPU401 are related to the BIOS configuration
and the parport_pc module parameters and are not regressions from
2.6.26, but please correct me if I'm wrong.

Thanks for your patience with all this.  I'm putting together an ISA
machine at home now, so hopefully I'll soon have a way to test this
better without wasting your time.
