Just as an aside, can we do anything to help people identify whether
their hardware is 64bit capable?

Not sure it is still that way, but at least a while back suse had such a check in the install iso boot loader, poping up a window saying somehing along the lines "cool (64bit) computer, do you really want to cripple it with 32bit software?". That was the box with a two-sided dvd though (one side 32 other 64bit). In *that* case it makes alot of sense, you just have to flip the dvd and it also avoids installing 32bit by accident.

For fedora you probably want to know *before* downloading stuff ...

Idea #1:
  Can preupgrade handle a i386->x86_64 switch?  If so a check could
  be added and offer going from F10/32bit to F11/64bit.

Idea #2:
  netinst iso for both 32 and 64bit, then have the bootloader check
  cpuid and offer either 32bit (32bit hardware) or 64bit+32bit with
  64bit being default (64bit hardware).

cheers,
  Gerd
