Thank you Paul.

nomodeset was accepted as a boot arg. radeon.modeset=0 was not recognized as a valid boot arg.

However, nomodeset did the trick. I now have X up under the auspices
of kernel-2.6.31-rc8.fc11.i586

Other observations:
after I edited the boot args and added the nomodeset radeo.moseset=0
and pressed b to boot, it took almost 3 minutes to get the login prompt.
Even after logging in, it took more than 1 minute to populate the screen with all my icons: about 55 of them.

Also, starting up Firefox and thunderbird also took considerably longer.
Sorry for not providing an objective time value in terms of how much
slower they started - should have timed them !

To provide some comparison with other kernels:
2.6.29.6-217.2.16.fc11.i586 boots to the login prompt in 1.5 minutes. 
2.6.29.5.191.fc11.586 booted to login prompt in 38 seconds.
On same dual boot machine, Windows XP boots to login prompt in
30 seconds.

Cheers,

MK
