FC3: Can't run 2.6.10 kernels with nvidia driver

[Frank]

I've tried each new kernel that has come out since 681, with the same 
result.  With a 2.6.10 kernel and the nvidia drivers installed, my 
system boots to a black screen and a dead keyboard when it goes 
graphical.  This is true on both 32 and 64 bit FC3, and this morning I 
tried the latest kernel with the driver patches mentioned here: 
http://www.nvnews.net/vbulletin/showthread.php?t=42964 , with the same 
result.

I don't care about 3D performance, but I do care about dual headed 
operation, and it seems that I need the vendor proprietary drivers to 
get that.  So I'm stuck there.

One of my systems now has a problem with USB mass storage devices, which 
I use a lot.  the first time I plug in a drive everything is fine, but 
subsequently no device will be recognized and there are no messages in 
/var/log/messages.  This worked just fine a couple months ago, so I'm 
guessing that something that needs the new kernels was installed, and I 
can't run the new kernels.

So at the monent, I can't run both a graphical interface and USB 
devices.  What a mess.  I'm starting to feel that FC3 is a bit too 
bleeding edge if I want to spend my time using rather than fixing my 
machines.

This particular machine is an Asus A8V with an Nvidia GeForce 6600 dual 
DVI card, running 32 bit FC3 (on an AMD64 processor).  Are other people 
having these problems?  Can anyone suggest how I might recover from this 
situation?
