I'm not sure if this will work, since both numbers are optional. In a name like
1:foobar
is "1" a device number or a drive number?
In addition to that, there are device numbers up to 31 (at least for the
CBMs), so your simple test is not enough (unfortunately).

I've read about it on the Contiki mailing list. Sneaking into the kernal
vectors somehow would have the advantage that the impact on the existing code
is very low.
