see ReInferno for some blob usage.

It doesn't appear to cover the new blob yet.

• The current version always runs serial at 115k (no switching)
• xdownload is available and expects the file via xmodem (no uuencoding)
• This blob can work with kernel-inside-filesystem so the instructions about downloading and flashing the kernel may not be relevant
• Never try to do two flash operations without a reboot between them
• There's a bug in blob which prevents it from receiving keys when you press more than one key to stop autobooting; so DON'T press more than one key when stopping autobooting!
