good news! I'll review the branch asap.

You actually don't have to try to cross-compile as the IRDA UART of the
Calypso in the Openmoko is attached to the earphone jack, just like in
the non-smartphone calypso designs.

But sure, it would be great to test it on both the MODEM UART (from the
s3c24xx side) and from the IRDA UART / earphone jack.

thanks a lot, I've started to read through it.

... assuming that nothing important is at the respective address in the
image, I suppose?  Do we have a way (by linker script tricks?) to ensure
that there is some bogus data at that location?  Last time I checked, I
could not figure out a way to tell the linker "start filling .text from
address A to B, then exclude B to C and continue filling from C
upwards".
