Ah, right, I should have read your message more thoroughly.
I think the only way you will get this information is from
a partitioning tool. If you run "fdisk /dev/hd?" (where ? is
the drive number), and do "p" to tell it to print the
partition table, it will tell you what units the partition
number are expressed in ("Cylinders of 512 * 8192 bytes" or
something like that). You can then use the total available
space in those units and a little multiplication to find
the available space in bytes. Or you could just create
a filesystem on the empty space (after making a partition
there, of course) and run df.

As for adding space to an existing partition, I guess there
are partitioning tools that will do that, but you might
have better luck with the "md" (multidevice) driver - it
lets you combine several partitions into a single
logical one, without having to mess with the physical
partitions.

Cheers,
