Hmm... well without breaking naming conventions i guess we could easily go
up to /dev/wd0z or the like ? ... or even wd0zz ... so thats not really
the issue... i guess one has to look at the encoding of the IOCTL to know
how big that field can be at a maximum... would like the 32 or so ...  i
know this is also an arbitrary number, but it's a 2^^6 instead of a 2^^4
so wont give that much trouble i guess, but then maybe 2^^8 is favourable.
The only programs that need to be pached is the bootloader i guess... and
maybe the bootblock loader.  For all architectures that is though ...
hmm... cant see the complexity of it now but it doest sound that

Idea's ?

Can't really imagine what to put on a 100Gb disc ... but then i thought
that also of my 4.7 Gb and i got once to a point that it was full (!!)
