FLASH RamDisk and kernel init options for disk

Hi,

What are peoples thoughts on the best way to make
a small ramdisk which fits in less than 1M and
performs the task of checking for a root disk,
running fsck, and then remounting it as root.

As a fallout condition, it would let your run
fdisk and possibly some network script which
runs rpm over the net..

The reason I ask is because I boot my kernel and
ramdisk from flash and would like to create a small
initrd that allows you to setup a system/disk if
it is not found.

Surely someone has done this ...

Also, is there some way to pass a kernel argument which
does an fsck on a disk before it mounts it every time?
I'm pretty sure this doesn't exist ..
