Ok, I'm looking at Dell's 'For Work' laptop site right now, and the 
M4800 is available with either AMD Firepro M5100 graphics or Nvidia 
Quadro graphics (two different cards are available).  The AMD Firepro 
card is the default option.  Ordering without the extra discrete 
graphics is not supported.

I'm using the stock EL7 Radeon drivers (NOT the AMD/ATI Catalyst fglrx 
drivers) on my M6500 on a Firepro M7820 card, and the thing works very 
well.  While docked it's nice to have triple monitor support through the 
dual displayports on the dock; the displayport on the laptop itself 
works very well also, with dynamic desktop configuration when you plug 
it in and plug in a projector or whatnot.  Better support than most 
Windows 7 machines I've seen.

If you order the M4800 with RHEL 6.4 and a one year subscription, it 
only adds $76.30 to the price; 3 years will cost you $335 (and while it 
says '6.4' you get the updates to get you up to 6.6 with the 
subscription, of course).  With an RHN subscription you should be able 
to install RHEL 7 on that box and enjoy the subscription.  Yes, Dell 
offers RHEL 6 preloaded on the M4800.  Ubuntu 12.04 LTS is also offered 
as a preloaded option.  See attached screenshot.....assuming the list 
allows it.....

Dell further supplies fully supported drivers for the graphics, both 
nvidia and AMD/ATI, for RHEL 6 (not yet RHEL 7, sorry).  Go to Dell's 
support site, and navigate to the Laptops/Precision Mobile Workstations 
and go to Drivers and Downloads.  If you'd like a screenshot..... let me 
know.
