booting from sdhc on acer aspire one

finally got my aa1 to boot with root on the sdhc card. these instructions are really good, and this reference is good, too. (though he is of the opinion that the nand flash write cycle limit is nothing to worry about, and i used to think that, too, but.... i wonder if my swap and ext4 fs had anything to do with the built-in ssd drive crashing so completely and painfully. this time i'll be going ext2 retro, just to be safe.) had to boot from a usb drive (yeah, ssd is that hosed... can't even spare a few mb for a boot partition. heck, i can't even alter the partition table.) but it seems to be booting. now i wonder if i can hack this case open and put the usb drive in the unused bay...
