Put one of these Radiotrack cards in my alpha.  Hmm, it doesn't attach.
Looking at the source (sys/dev/isa/radiotrack.c) the rt_find() routine has
`#if 0' around the code that tries to detect the card.  Took this out and
saw why - it took roughly 400 seconds per card to determine that I didn't
have cards at the other addresses (rt0, rt1, rt3).

Changing the step from 10 to 100 speeds things up - 40 seconds to probe
cards that aren't there and 20 seconds to find the card (with its aerial
removed).  Would taking out the `#if 0's be OK, along with changing the
kernel configuration to something like :

#rt0	at isa? port 0x20c	# AIMS Lab Radiotrack & compatible;
#rt1	at isa? port 0x284	# probe is slow; add only if you have one.
#rt2	at isa? port 0x30c
#rt3	at isa? port 0x384

aka ISA joysticks?
