The problem is that the current script is not very modular. There are
many places where the device-name is matched against [hs]d[a-z]. Many
checks also imply that a device ending with a number is a partition, not
a disk. Both assumptions are not correct with SmartArray devices
(/dev/ida/c0d0, /dev/ida/c0d0p1 and /dev/cciss/...).

I have only fixed some of those checks, those that were in the code path
for installing lilo in the MBR.

Note that HP/Compaq Smartarray controllers are very common devices. I
believe it's better to support them for the most common case than not to
support them at all. Currently the postinst script just exits with an
error. (Handling the non-supported case would be fine, of course.)

Of course the best solution would be encapsulating and centralizing the
checks into functions but that's a rewrite of the whole script.
