Yes, because the larger Archos software in the FM leaves us 12 KB less space
for an uncompressed Rockbox image, and this is not enough.
As I've posted before, the V2 recorder has 4KB less left than the V1. Again
no fit, but this can be achieved by some optimization.

Jens is currently measuring this. We have ~10% more buffer, so the saving
can only be in that order of magnitude. Not too much, but if it comes for
free...

No risk. It's the same layout as before. But the Rockbox image doesn't get
decompressed to RAM and executed there. Instead, it is directly started.
This feature exists in my bootloader since the beginning, I just haven't
used it so far.
