I know of the MTD driver yes, I did actually disable it in my kernel
that I built using openwrt 'doh'.

Could you give me more information int his regard? You just got me very
excited ;)

I enable the mtd driver, then what? Even though my WRT54g was using mtd
for years, I never really got into it.

What flash is being used though, something from the board? Or is the IDE
disk used as an MTD device? Or is the extra portion of the flash used as
an mtd device?

So many questions! :D
