It is believed that all or most R400 laptops are compatible. See notes about CPU compatibility and switchable graphics for potential incompatibilities.
There are two possible flash chip sizes for the R400: 4MiB (32Mbit) or 8MiB (64Mbit). This can be identified by the type of flash chip below the palmrest: 4MiB is SOIC-8, 8MiB is SOIC-16.
The R400 laptops come with the ME (and sometimes AMT in addition) before flashing libreboot. Libreboot disables and removes it by using a modified descriptor: see gm45_remove_me.html (contains notes, plus instructions)
Flashing instructions can be found at ../install/index.html#flashrom
The R400 is almost identical to the X200, code-wise. See x200.html.
TODO: put hardware register logs here like on the X200 and T400 page.
