	System has a pair of EIDE drives merged via ccd.  Writes to this
	partition occasionally yield
savecore: reboot after panic: biodone already
	but I don't know how to usefully debug this further.

	untar large file on the ccd'd drive.

	The controller is one of the Promise controllers supported by the new
	pciide driver, but it has a local patch (taken off the NetBSD mailing
	lists) to coerce the IO area under 0x8000, because this is apparently
	necessary on this system.
