Comment 5 for bug 116267

Description of problem:
The b44 module with kernel-2.6.18-1.2693.fc6xen doesn't work:
b44.c:v1.01 (Jun 16, 2006)
ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17
b44 0000:03:00.0: No usable DMA configuration, aborting.
ACPI: PCI interrupt for device 0000:03:00.0 disabled
b44: probe of 0000:03:00.0 failed with error -5

ifconfig/ifup fails on this device, even though the module is loaded:
# lsmod | grep b44
b44 34133 0
mii 9793 1 b44
