Thankfully quite happy with dpkg, so it may be time to give it a go. Having
just popped back up from lower down (will make sense if you continue reading!)
are the module packages to install with these, or given that the kernel
versions match, are the Ubuntu ones adequate? I'm assuming the latter, but if I
use a newer kernel then modules would be required.

I've got a feeling that in the deb line in sources.list you could specify a
particular package to pick from the repository and not take the lot. I can't
find the reference now to see if my memory serves correctly, backports.org
seems the most likely source!

Already on that, given I've used Debian for some years now, so will likely use
that for now.

I was avoiding mentioning my previous provider, in case I say something less
complimentary about them at some point!

Personally I have no issue with being responsible, so long as I have some
guidelines to work to regarding the underlying VM requirements :) On which note
I'll head back up this reply with a comment!

Thanks, it is a while since I did much kernel compilation, in fact I'm not 100%
sure I've bothered since I moved to Debian. Back on Red Hat it was, from my
first Linux install, a requirement so that I could use the Token Ring NIC
drivers! Those were the days!
