Yes. But in some cases (of motherboards) you'll have to turn off that disk
in the BIOS setup.

2.4 kernels had CONFIG_IDEDISK_STROKE optikon for geometry resizing of big
disks. It seems that 2.6 kernel does that automatically (or at least, using
option hdx=stroke). You could even try to boot from the disk and have /boot
there, just make BIOS think it's smaller disk than it is...
However I don't think you should have root partition bigger than 32GB - my
root partitions are usually smaller - I use /var, /home (ext3) and /tmp
(tmpfs) on extra filesystems.
