You need an iPAQ with 32MiB of flash for now. Better compression routines
are easy enough to plug in (hint hint).

To install it, first bunzip2 the jffs2 and kernel images, then:

'load kernel', send zImage
'eflash 0x1600000 0x0a00000' to erase the end of the flash
'load flash 0x100000', send jffs2 image
'set linuxargs "noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySA0"'
'params save'
'boot'

You probably then want to install the fonts.
