The latest MacBook equipped with a Core2 Duo and the Santa Rosa platform, dubbed MacBook3,1, is now partially supported by pommed, thanks to Paul van Tilburg who sent me the data I needed yesterday. It is available in the pommed SVN, but read on.
As with the last MacBook Pro refresh, I do not have support for the LCD backlight yet. It may or may not be supported by the ACPI video driver; if someone has access to a new MacBook and can test that and report back, that’d help.
Note that you’ll also need to patch your kernel, because Apple changed the keyboard and trackpad in this refresh. The new device is called Geyser IV-HF, and according to the Info.plist from the OS X kext, it’s compatible with the previous Geyser III and Geyser IV devices – you’re lucky. USB IDs for the new devices are 0×0229 for the ANSI version, 0×022a for the ISO version and 0×022b for the JIS version.
This refresh also brought a new iSight, USB ID 0×8300. The Apple IR receiver hasn’t changed (USB ID 0×8242).
