I currently have the 32bit version installed on my Dell Xeon.  I
didn't know it would support the 64bit version.  Is running the 32bit
supported?  Would I experience any problems (other than a lack of
64bit capabilities)?

I see three versions, I assume the correct one is the  AMD64/Intel EM64T one?

Red Hat Enterprise Linux ES (v. 4 for 32-bit x86)
Red Hat Enterprise Linux ES (v. 4 for 64-bit Intel Itanium)
Red Hat Enterprise Linux ES (v. 4 for AMD64/Intel EM64T)

Thanks
