The start sectors are aligned to be %8 clean and the to the cylinder boundary. So far I did not had any trouble with that setup on 4G SD cards (did not try on 8G cards though). For MLO loading I think only the start address might matter... not sure
Aligning to 8 sectors is not going to help at all, that is much smaller than the normal erase block size (4MB) and also smaller than typical page sizes (8kb or 16kb). If you want good performance, you should always align to 4MB or more. Using the regular geometry (255/63/1024), that will never be cylinder aligned, which is ok. Don't try to do cylinder alignment.
Hrm - does that also have any implications on not being able to boot from the beagleboard? :)
I only know of one bug on beagleboard where an old xloader requires the boot partition to start at sector 63 independent of the geometry. It is well possible that there are other bugs though.
