Thanks to those who sent their suggestions.  In fact it helps
quite a bit that there is no other device on IRQ 9 ;-)

OOPS!

On a slightly related topic:
The WD8013 does seem to exhibit odd behaviour as the kernel only detects
the card from a cold boot / power up.
One person who responded mentioned this problem.  It is wide spread?
Is there a fix?

The problem is that a warm boot does not cause a card reset.  This is
arguably a defect in the card.

The probe routine could be modified to forcibly reset the card; however, if
this is done, what is the point of having a probe routine (since you must
assume the card is present to reset it)?

Th appropriate answer is a shutdown routine for drivers in each device
driver... no one has hacked this into the device interface yet.  This
would also allow a spin-down of disks or "parking" the heads, if the
shutdown took an argument.

Happy hacking!

Is there a reason for not using outb(0x64, 0xfe) in reboot ?
To my knowledge, this pulses the reset-line on the whole system
and everything resets to a known state (hopefully).
The 0x64 is on the keyboard chip ?

Well, the ie device driver that I have written does precisely
this---that's how it determines that the card is actually there!  (It
also reads a description register from the StarLAN cards as a
preliminary determination.  If anyone knows how the configuration
parameters should differ between StarLAN and Ethernet, please let me
know!)
