[ILUG] Checking how much DVMT memory is in use

[Rafiq_Maniar at Dell.com]

Hi guys,

Any idea how to check how much DVMT has robbed from system memory at any particular moment? 

dmesg shows how much memory is taken on bootup:
agpgart: Detected an Intel 865 Chipset
agpgart: Maximum main memory to use for agp memory: 202M
agpgart: Detected 892K stolen memory.

But i'm sure this would have increased once X/etc has been started.

Cheers
