Just to report my results, I tried supplying 5.5v on the roboaudio
header (v_robobatt). That seems to do the trick, the gumstix boots up
with the wifistix-cf attached.

During uboot it was drawing ~360mA, then jumped around as high as
450mA while loading the kernel and during the kernel boot it was
around 380mA - spiking once up to 450, probably while searching for
wifi networks (I didn't have the antenna attached as there are no open
networks here).

When the gumstix entered the idle loop it settled at around 215mA (if
my short-term memory serves me right, might have been 315).

Thanks for your help Dave.
