Not exactly true, probably Linus didn't want to spur too high expectations.

The MAS has a bug, you could solder in a more recent chip to really resolve
the problem. All Archos have the older, buggy version.

Or Rockbox does a similar workaround like the Archos firmware does: It
tracks the frames of incoming mp3 data. In case of a mismatch the MAS gets
restarted. Results in a minor glitch in the recording, but will hardly get
noticed, as rare as it happens.

The latter has been discussed on IRC, perhaps will get implemented one day.
