Re: Patch to support drivers compiled into the kernel

I'm sorry, it seems the list manager did not deliver all the replies Kay
Sievers quoted...

In regards to the device particulars, I have included the output of
hal-devices below.

As you can see the network device is:

13: udi = '/org/freedesktop/Hal/devices/net_00_ff_d3_da_b0_00'

The originating device is:

net.originating_device = '/org/freedesktop/Hal/devices/computer'

I don't know much about HAL, but this appears to just be a reference to
the Linux kernel, so there is no driver associated with it.

The other option I considered is just to return "<unknown>" in all cases
when the driver is not found, but I worried that might have un-intended
side effects.
