Something I discovered
Please feel free to send me your findings, especially on different models. In order to ease your work, I prepared a small program that you can download and install: it will produce a small file that you can send to me. Instructions are enclosed in the zip file (if you are experiencing problems with the latest 7.xx and 8.00 versions of the tomtom firmware (i.e.: if the altimeter icon does not show at all in the menu, please read here).
It appears that /proc/barcelona describes the hardware at hand, while /mnt/flash/sysimage contains factory settings.

WARNING: firmware version 6.x break this table: it has a lot more files, and /proc/barcelona/battery is missing
Notes:
1 Thanks to cd at maintech dot de, one of the developers of OpenTom
2 sent to the CSR Bluetooth chip by csrinit
3 the touchscreen drivers will take care of it
4 The devices with the new button have a shorter power-on time
5 It is broken somehow. It gives me a segfault when I try to cat it; cd at maintech confirms
6 380 MHz ARM processor
7 200 MHz ARM processor
8 Thanks to Marco Briotti
9 Thanks to IHnet
10 Paul Mansfield reports that this has to be at least 16 bytes long. I confirm that on the devices I checked it contains a zero-filled string, where the first bytes contain the ascii representation of the version number, and the others are all 0.
11 It seems, at least to me, on the rider and the go 300, that the standard ttn application takes care of sending the calibration data to the touchscreen; after that, it can be read without caring of calibration
12 It's 6 bytes long, containing a binary representation of the MAC-address
13 Of course, since the Go has no bluetooth, wifi, ethernet, or similar devices requiring a MAC address, this file desn't make sense on this model
14 Thanks to Daniel Besoli
15 320 pixel wide, 240 pixel high, 16 bits per pixel
16 it's actually a 240 pixel wide, 340 pixel high, 16 bits per pixel display, mounted rotated
17 Actually, it appears that the tomtom 730 ignores the /SdkRegistry directory on the SDcard, but it reads startup files from its internal memory only
18 Thanks to Richard
Moreover, thanks to Cedric for some more hints.
