I have 3 linux computers, 2 64-bit desktops and one 32-bit laptop.  

The laptop (an old Dell I4100) works fine with FC5 kernels 2145 and 2157.  

One of my 64-bit desktops (Athlon based) shows the exact behavior you describe
with both kernels, but works fine with kernel 2122.  When running 2145 or 2157,
I can get into it using ssh over the network, but the console monitor is turned
off.  

The other 64-bit desktop (P4 based) simply won't boot with these two kernels,
ending with kernel panic during initrd.  It works fine with kernel 2133.

I am not a linux guru - but if this is still an issue then please let me know
how I can assist.
