Bootloader
After some poking arround with minicom on the serial port, I got to see some bootloader messages. Minicom config was 115200 8N1 ANSI.
I get this when I soft reset

CPU ID = C0 Bulverde
Run Mode = 208 MHz
Turbo Mode = Run Mode

Boot FLASH in Asynchronous mode
Got Soft Reset
And this when I hard reset('home' + 'mail' + reset)

Tried many button combinations while resetting but couldn't get the bootloader to interact/do anything else. Pressing space does nothing either.

Just some additional random bits:
You can get the PDA into reflash mode by keeping the power button pressed after a hard reset. It will then try to find a boot loader file (EBOOT.BIN) or a directory called "ACER_N50" with a ROM update (CHAIN.LST + ROM images) on either a CF or SD memory card. There's also support to download these files via TFTP when a specific kind of CF network card is plugged in.
If there's only a USB cable plugged in, the bootloader will try to get the update that way, although I haven't been able to figure out how this is supposed to work. Update via serial cable should also be possible, but the bootloader really doesn't react to any key presses.
Except from booting itself the bootloader is quite unstable and will easily crash the PDA leaving some flickering patterns on the screen if it can't find any CF or SD card, but this shouldn't do any damage to the existing ROM data.
