Fraid I can't, since the Balloon currently doesn't do more than get into
its bootloader.

Linux was a short lived Fluke - the bootloader can't see the NAND chips
at the moment.

Using a PSU I borrowed from Wookey, and I presume that should be Ok. It
doesn't state its max current output on the supply.

Since it boots Ok with a different boot loader, is it OK to presume that
the powersupply is good?

Standard build AFAIK, didn't have a CF card in when it played up. I did
have a CF card in at one point whilst it was working, but owing to me
not knowing the root password of the disto (rootme), I didn't get to see
if it would mount ok.

There are two MAX604s on the board next ot the USB Connectors.

Thanks - looks like I may need it!
