vs 2.4:

Note that 2.6 found 0xa0000000 to 0xa0ffffff clean, but 2.4 didn't.
As a temporary work-around, could you look at /etc/pcmcia/config.opts,
and remove the memory range 0xa0000000 to 0xa0ffffff please?  IOW,
comment out:

include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff

and insert:

include memory 0x60000000-0x60ffffff

Meanwhile I need to work out why 2.4 (seems to) correctly mark the
high range unavailable, yet 2.6 doesn't.  This means I'll need to
send you a patch which will need testing, though this'll have to
wait until tomorrow.

In the mean time, if you could confirm the above, that'd be most
helpful.  Thanks.
