Claim Topic TP560 data/fax/voice modem. This device reports as class 0x0780, so we don't claim it by default:
00:0d.0 Class 0780: 151f:0000 Subsystem: 151f:0000 Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at a400 [size=8] 00: 1f 15 00 00 01 00 00 02 00 00 80 07 00 00 00 00 10: 01 a4 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 1f 15 00 00 30: 00 00 00 00 00 00 00 00 00 00 00 00 0b 01 00 00
Some rc.serial scripts extract IRQ and I/O port information from /proc/pci and stuff it into an unused port using setserial. That doesn't work reliably anymore because pci_enable_device() is never called, so the IRQ may not be enabled.
Thanks to Evan Clarke for reporting and helping debug this problem.
