Ok, we just got our MO's to work with both 2.0.29 and 2.0.30
kernels. Look at www.linuxhq.com for the unofficial patches
for the 2.0.x kernels and there is one for 2048k sectors.
However, we could not get the kernels compiled with this
patch to work. 

But apply the patch found at http://stud1.tuwien.ac.at/~e8826423/Linux/
which though it targets the 2.1.26 kernel, patched both 2.0.29 and 30
here. (two patches fail, but they relate to cd rom changes and
we reasoned that since the cd works now at worst it could break :)

The kernel then compiles and recognises the drive at boot, and the 
media. We have created ext2 filesystems and been able to use data
from them without problems. Also we can mount vfat disks and read 
and write to them (hey sometime win95 compat. is a necessary evil).

hopefully, the patch will soon make it into the kernel distribution
and I can sleep better.
