[PlanetCCRMA] remove .rdt packages from apt-get update (wont boot)

[nigel henry]

Hi Fernando. I have a problem with the .rdt kernel packages. 2.6.9-2.2rdt 
wouldn't boot with an IRQ14 (IDE controller 1) bug. Same with 2.6.10-0.1.rdt. 
Is there a way to remove them off the apt-get dist-upgrade as DLing 40MB+ on 
dial-up seems a bit pointless as they wont boot on my hardware (It's these 
cheap pre-installed Evil Empires XP machines). All the other kernels are ok 
on FC1 and FC2. I'm working with apt on the command line not synaptic. If 
this is easier on synaptic I'll use that. Perhaps you could explain what it 
is with the .rdt kernels that might be causing this problem.
Machine is Aifriend with a Celeron 1300MHZ processor and 1GB RAM. Audigy2 
soundblaster sound card.  Nigel.
