OK, I see now.

Nope, contrary to the 2.4 series the vendor mods to the 2.6 kernels are 
very low.  Actually by copying Fedora's kernel config file you are 
compiling with the same options as Fedora.  The only thing you won't 
have are any additional patches that Fedora used.  None of which (if 
any) seem important to a MythTv installation (at least that I have found 
anyway).  The make oldconfig will bring up any new questions between 
Fedora's shipping config and kernel 2.6.7.

Because 4k stacks are the future of the kernel.  They are optional in 
the kernel.org kernels for now, but it has been said that in the future 
only 4k stacks will exist.  Fedora is just getting everyone used to it 
now.  One of the major distros had to bite the bullet and go first.  
Amazingly it affected very few things.  Unfortunately it was everything 
that we/I cared about (nVidia, ivtv, and XFS).  BTW, it only 
*potentially* affects XFS if your XFS partition gets full.

Yes, you will need to recompile the nvidia drivers, but that is a piece 
of cake.  There are a couple of things you can do.  Probably the easiest 
is to change your init default to 3 (/etc/inittab id:5:initdefault: 
change 5 to 3) before rebooting after installing your new kernel.  Once 
you've rebooted, install the nVidia drivers, then init 5 to test it.  
Don't forget to change your init default back to 5.
