Hi
I have exactly the same problem with exactly the same notebook
seems that this problem is pretty ugly

check this out: http://lists.freebsd.org/pipermail/freebsd-mobile/2008-May/thread.html
for mails with subject: bge and wpi do not function on aspire 5920 
and this: http://lists.freebsd.org/pipermail/freebsd-acpi/2008-May/thread.html
for mails with subject: PCI bridge with I/O decode 0x0-0x0

so far there is no clean solution but very dirty hack
a guy from the freebsd-acpi list and I are trying to at least find the problem
if you have some ACPI knowledge you could help too
please post here your ASL code (which should be identical to mine)

thank you

Regards
MGP
