Si, ha arreglado varias cosillas la verdad. Pongo aquí el changelog, que más de uno preguntará si no

Esto sí vale para CM7/MIUI!
- Cleanup.
- Fixed buttons freezing randomly.
- Fixed media buttons / headset buttons.
- Lots of GPIO fixes which eliminate phantom keypops.
- Added updated sysfs interface for smartass governor.
- Updated screenstate scaling script to use non-deprecated sysfs
interface for smartass2 and other govs.
- Back to CM7 LED Notifications.
- Lots of changes to cypress touchkey driver to guard against phantom
keypops and speed things up.
- Removed CarrierIQ-related virtual serial device. It probably wasn't
used, but now we know for sure.
- Changes to dpram (modem <-> kernel interface) to make the radio a
little more stable.
- slightly more helpful gamma table error message.
- Moved call audio sysfs files from voodoo sound group to their own.
- Integrated 90call_vol into the kernel zip file so people don't
have to mess with it on their own.
- Now possible to choose any governor as sleep governor in the recovery.
- Vandalized bootlogo a bit.
