Subject: [PATCH] 2.6.17.9: Add VIA quirk fixup for VT8235 usb2


Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235
southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after
no-IRQ?" error and the device is unusable.

Signed-off-by: Mark Hindley <mark@...dley.org.uk>

I belive this could also be a fix for Bugzilla Bug 5835.
