The flasher for Linux should work on both phones, I think the older 'tablets' too.
There is flasher-3.5 from Nokia and 0xfff a FOSS implementation of flasher which is on most linux repositories but uses slightly different commands.
I always used Nokia flasher-3.5 because most of the documentation on TMO and the wiki are for that vs 0xfff.
(edit) OK I see it, fixed to maemo_flasher-3.5_2.5.2.2_i386.deb
thanks for noticing that!!
