There is nothing to debate, those that need it
know why. Great idea!

Gumstix has no fs support for ext2 compiled in,
if it did I would reformat a mmc to ext2. I never
thought to check into it but can you use jffs on
mmc?  Now the MMC is mounted as vfat.

I would like to review the linux mmc driver. 
Even with single bit 20Mbps should give a couple
of MB/s which is on a par with the flash write
speeds of the average nand chip.  If you
pre-erase you can get faster but this seems
practical for datalogging and pictures only.

You might want to develop on something like a
NSLU2 with a USB2 drive. Or some ARM SBC with a
IDE port then migrate to the gum.
