GNU/Linux, firmware update, possible ?

Hi All,

I about to buy a new mp3 player. I am about to purchase the Sansa express, but have one doubt.

I running GNU/Linux, (Debian, Lenny). I have no access to a windows machine.

From what I have researched to complete a firmware update on the CLIP (Not Express), in GNU/Linux I extract the fimware. bin (e.g. m300a.bin)…

And place this file on the root of the mp3 player flash memory and just umount.

Is there a way to update the express firmware on GNU/Linux. 

Can anyone confirm ? Do not want to but a device I can not update and I want to use 4GB microSD cards. Otherwise the express fit exactly want a need (playlist slection, genre, expandable storage, low price, reliable)
