There's a long list of things that are updated in RHEL5.  Are you more  
interested in server or workstation/laptop aspects?

Some of the things I can quickly remember, but there are many many more:

SATA hotplug and NCQ support (hardware dependant)
hibernate support (older implementation unfortunately, but seems to work)
resume from suspend finally works on my old laptop ;-)
NetworkManager finally usable with most (all?) wireless cards
Xen (virtualization) part of standard distribution
