There are two sections to the flash memory. (the Big ROM, and the Small
Rom)
The Small ROM houses the that 'debugger' mode you were talking about.
The Big ROM houses the the collection of PRC files that make up
"PalmOS".

You can re-flash your memory the hard way with Linux, and prc-tools.
See here:

There's also a somewhat better way off those romeo pages.
FWIW, (albeit this is unsupported and will void any warranty you may or
may not have on your Palm) you can sign up for the Palm Developer
Connection, and download Rom Images for the Palm Emulator. Said Images
work reasonably well in a 'real' Palm. (At least that's how I got a
IIIxe, and a III upgraded to 4.01.)
