Well, I believe you told me that you got the accelerated "nv" X driver
to work with the YDL 2.1 2.4.10-12a kernel by just using the "novideo"
option, and that kernel does have EXT3 enabled in its .config, but newer
kernels are probably better for such advanced features.

Well I guess that blows that idea.  :-(

I would have thought that it should work OK.  Maybe you would need
to rebuild the 2.4.10-12a kernel from source.

Did you see the post from the guy who said he got the IBM java stuff
to work with the 2.4.19-pre8-ben0 kernel by enabling SMP?  If true,
that sounds like a kernel bug to me, but it might be worth a try.  I
couldn't do that myself since I actually have an SMP machine, and I
like to run MOL which isn't SMP safe yet (plus the X may not even work
on an SMP system with SMP enabled).  BTW I did a quick grep of the
kernel .config and the only memory option I see is CONFIG_HIGHMEM.
