When I remove 'quiet rhgb' parameters when booting, all I get is  "Booting a command list" and then nothing, just that same text on a black background. The light on the USB stick flashes for about 1.5 minutes, then stops. And the computer gets really hot, and the fans eventually shoot up to max and the thing sounds like a hairdryer.

What does "lspci -nn" say, particularly for the video graphics card?
What does F18 say in syslog /var/log/messages regarding any 'conflict's
in address space during initialization of the linux kernel?

If the box has a serial port, then connect a null modem cable
between the serial port and the serial port on another machine.
On the other machine run 'minicom' and turn on logging: <Ctrl>A Z L
On the problem box, append " console=ttyS0,115200 console=tty0" to the
boot command line, and boot.  See linux/Documentation/serial-console.txt.
