We're also having no problems with the EFI partition configured to type b
(Win32 VFAT). We have, however, run into problems using Microsoft's EFI
fdisk & format utilities, so in our lab, only use the Linux installer
fdisk/disk druid utilities to create the partition.

This sounds like the problem I had when I first installed 7.2 - every kernel
I built panicked, because I hadn't applied the ext3 patches to the
kernel.org kernel sources. As soon as I put that support in (and selected
it in my configuration), the kernel panics went away. Not sure if this is
what is plaguing you, but wanted to share that the symptoms are similar
(although this only happened to me in 7.2, as 7.1 didn't have the ext3
support built in.
