Graphics Stolen Memory and TSEG are within DRAM space defined under TOLUD.  
From the top of low used DRAM, GMCH claims 1 to 64 MBs of DRAM for internal  
graphics if enabled.  
The base of stolen memory will always be below 4 GB. This is required to prevent  
aliasing between stolen range and the reclaim region.

Base of Stolen Memory (BSM): This register contains bits 31:20 of  
the base address of stolen DRAM memory. The host interface  
determines the base of Graphics Stolen memory by subtracting the  
graphics stolen memory size from TOLUD. See Device 0 TOLUD for  
more explanation.
