OK, since you and magnus are having the same issue, and at least one 
other has confirmed a similar or same condition, we have enough to drop 
the problem out of the anomaly real, and into something related to a 
recent update (or something similar).

I have another piece of info that may or not be related:

The 2.6.20 kernels will NOT enable the ethernet driver for anaconda 
properly.

I use:

linux text ks=http://server/ks/developer.ks

to begin an install.  On three different systems now (all attempts I 
have tried) this fails with interface failures.  F3 shows DHCP READ 
fails because network is DOWN, yet F4 shows the network up normally.

I roll my own initrd.img with the current kernels using pungi, and this 
behavior began with 2.6.20 kernels.

The problems together indicate a larger issue with the basic ethernet 
drivers in the 2.6.20 kernels.

So, the acid test is for you to boot an older kernel, check the problem, 
boot the latest kernel, check the problem.

Is it a kernel (newer basic ethernet driver) problem?

Can you try a pre 2.6.20 kernel?

If it works, then we need to check bugzilla ...
