Yes good. I had thought it would be fine to use that.

The problem I have with this kernel is that floating point emulated
instructions which perform stores seem to be falling over. There is
a bug in the fault handling code for stock 2.4.21 that I am using it
would seem but am looking at whether it is worth fixing it.
By all accounts I might as well just use the floating point emulation in
libc but am still interested in enlightened feedback.
Cheers,
Jon.
