I suggest that you test 2.6.22-rcN using one or both of these
boot options:

noisapnp
pnpacpi=off

Somewhere between 2.6.18 and 2.6.22-development, the ACPI config
symbol also starting enabling (selecting) PNP.  That's one of many
differences....

with the 2.6.22-rc4 kernel that I was useing earlier, adding these two
options clears up the problem. Thanks.

should I test the two individually? or just plan on useing both from now
on?

Yes, please test them individually.  I expect that just one of them
will suffice, but I don't know which one.

pnpacpi=off works
noisapnp doesn't work

I normally disable PnP (both ISA and PCI), should I leave it enabled with
the newer kernels and this motherboard?

ACPI recently began enabling (selecting) PNP for you...

I didn't realize this had changed.

How do you normally disable PCI PNP?

What kind of hardware is this?  Please show us lspci output.

I would also disable CONFIG_USB_USS720, at least for testing.

for ease of testing (I got time to reboot the box around midnight) I used
the same config as before, so this is still on.

 I haven't had time to bisect this, but I'm having a problem on a
 AMD64
 gentoo system where the printer doesn't work with recent kernels.

 2.6.18-rc3 worked
 2.6.21.1 doesn't
 2.6.22-rc4 doesn't

 unfortunantly the system is gooted on 2.6.18 at the moment and I'm
 out of
 town so my ability to test is limited I can provide the 2.6.22-rc4
 (attached) and 2.6.18-rc3 configs.

 dmesg appears to show the port being detected, but writes to the
 port
 under newer kernels appear to complete, but no data gets to the
 printer.

 any suggestions other then doing the large bisect?

 That would be good, thanks.  Please be sure to cc linux-usb-devel on
 the results.

 OK, I'm curious about how someone deduced that this is a problem
 with a USB printer vs. parallel port printer since the config file has:

 CONFIG_PRINTER=y
 CONFIG_USB_PRINTER=y

 The kernel boot log should probably be posted also.

 here is the dmesg from 2.6.22-rc4 and kern.log showing 2.6.22.-rc4 and
 2.6.180rc3

 the printer not working is the parallel port.

This email didn't show up on lkml or linux-usb-devel due to size limits (it
was 900+ KB).

David, please send your working 2.6.18 config file.

Can you post the kernel log files on the web somewhere?
