Newbusify the driver.

Add support, kinda, for megaheartz xjack nic cards.  This support
works well for one machine per ethernet segment because it hard codes
the MAC address.  The pccardd in -current doesn't have support to
parse the ethernet address from the CIS in the funky way that the
megaheartz card does things (it includes it in the info tuple, as
ascii, which is non-standard).  I'd rather kludge this for the moment
and work to read the CIS from the kernel rather than mess with
pccardd.

The isa attachment is untested.  The pccard attachment is known to
work since I'm committing over it.
