Hello! :-)
I tested your patch, works fine! :-) Though I have a problem with pciutils:
lspci works fine:

Reading with setpci works also fine:
# setpci --version
setpci version 2.2.4
# setpci -v -s 0:1f.0 a4.b
00:1f.0:a4 = 01
But writing doesn't work:
# setpci -s 0:1f.0 a4.b=0
setpci: obsd_write: ioctl(PCIOCWRITE) failed
I use i386 -current, basically with a GENERIC.MP kernel, but with ACPI
enabled. I tried also -release and -current, both with GENERIC kernel,
with the same results. Reading works, but writing doesn't work.
What did I miss? Do you know this error? And what can I try to make
writing this register work?
Thank you in advance for your help!
Tas.
