It should be interesting to have results using driver 3.0i and 3.1a on the
same kernel version and configuration, for example:

- linux-2.1.126 that has driver 3.0i
- linux-2.1.126 patched for driver 3.1a

Patch location:
ftp://ftp.tux.org/pub/roudier/ncr53c8xx-3.0i-to-3.1a-for-linux-2.1.125.patch.gz

And you may want to also compile the kernel using gcc-2.7.x if driver 3.1a
has the timeout problem. If booting with tags disabled, asynchronous
transfers, etc..., makes difference, this may also help find the cause
of the problem.
