Yes, according to my coworker, Windows Embedded boots fine. And the
system boots via the card, with syslinux loading the kernel/initrd from the
card, so I don't know why it wouldn't be ready.

As I mentioned before, 'sdparm --command=capacity /dev/sda' initially
fails, but will succeed after 'sdparm --command=start /dev/sda'. However,
even though capacity works after the start command, attempts to access the
card continue to fail (e.g fdisk -l /dev/sda).
