Bug #6332 filed against ACPI.
As far as the part of the output which details the lack of IO address,
I'll leave that to Alan Stern... I'm not quite that advanced at this point..
Thanks for the help!

I have an Averatec C3500 Convertible Tablet PC. With the initial bios
version that ships with the unit, USB and PCMCIA both work fine in
linux. However, there is a terrible keyboard lag and dropped keys. The
follow-on bios revisions fixed the keyboard issues, but caused USB and
PCMCIA to both stop working. Note: All devices continue to operate fine
in Windows. I'm posting this here in hopes that someone will take
interest in this issue ( there are several others trying to use linux on
these laptops. ) I've captured dmesg output after enabling
CONFIG_USB_DEBUG and CONFIG_PCMCIA_DEBUG in the kernel config, and the
output from lspci -vvxxx, as well as the DSDT output from both the
original BIOS ( USB working / Keyboard not ) and the latest BIOS
revision ( USB Not working / Keyboard works great ).
The link for all this captured data is: http://www.linuxkidd.com/c3500
I've detailed the machine hardware, running kernel, etc.. as well as
linked to all the above described captures.
Thanks for your effort in debugging this. Can you please open a
bug report at http://bugzilla.kernel.org?
After posting the above request to the linux-usb list, Alan Stern
responded with:

According to the log, the I/O memory mappings for the USB and PCMCIA
controllers aren't getting set up. It's not a USB or PCMCIA issue at all;
you should ask for help on the PCI and ACPI mailing lists.
I don't know enough about USB to know what you're referring to.
Can you point out the messages that suggest a PCI or ACPI issue?
