I actually had something to that effect in my rc.sysinit file.  It unmounted
/initrd, removed it, and attempted to flush ram0.  I started trying it
manually when that didn't work =(

Funny thing though (not entirely unexpected)--/initrd's not in /etc/mtab.
I can see why.  Also, /proc/sys/kernel/real-root-dev is still 0x0100
(/dev/ram0).  Changing it to 0x0301 (/dev/hda1) doesn't help, but it might be
a clue for those who know this stuff better than I do.
