	Although the txp0 is found and reported at boot time, an attempt
	to ifconfig it causes kernel page fault with txp0 being the "current

	Manual ifconfig or through dhclient -- does not matter.

	I first observed it while installing the RC and then (after
	installing over a different NIC) confirmed on a functional system.

	Here it is:


	txp0: <3Com 3cR990-TX-95 Etherlink with 3XP Processor> port 0x8080-0x80ff mem 0xff380000-0xff3bffff irq 16 at device 10.0 on pci3
	txp0: Ethernet address 00:01:02:68:53:e7


	txp0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
		ether 00:01:02:68:53:e7
		media: Ethernet autoselect (100baseTX <full-duplex>)
		status: active

	The card, of course, worked perfectly in a i386 box for years.
