Yes, it does.

Moreover, 2.6.10-rc1 has this problem too, but here the network adapter
stopped working along with the USB (as you can see above, it shares an IRQ
with the USB too). Also, this time I was able to reload the ohci-hcd module
(it didn't help) and I got these messages:

Different ACPI or APIC settings may help.

Oct 23 18:42:45 albercik kernel: Intel ICH 0000:00:06.0: Device was removed
without properly calling pci_disable_device(). This may need fixing.

The "control timeout on ep0out" and "Unlink after no-IRQ?" messages are
puzzling, but the last one is just ridiculous as the box has _nothing_ to do
with Intel.

The .config for 2.6.10-rc1 is available at:
http://www.sisk.pl/kernel/041023/2.6.10-rc1.config
The .config for 2.6.9-mm1 is available at:
http://www.sisk.pl/kernel/041023/2.6.9-mm1.config

The outputs of dmesg and lspci requested by Zwane will follow in a couple of
minutes.
