NVIDIAバイナリドライバでは、GPUが使用できるシステムRAMの量を指定できません。私もnouveau
これが許されるという言葉を聞いたことがない。
NVIDIAドライバの最新の安定版のオプションは次のとおりです。

NVreg_MemoryPoolSizeは興味深いようですが、必要ではありません。
* Option: MemoryPoolSize
*
* Description:
*
* When set to a non-zero value, this option specifies the size of the
* memory pool, given as a multiple of 1 GB, created on VMware ESXi to
* satisfy any system memory allocations requested by the NVIDIA kernel
* module.
ただ楽しんで次のようにしてみましょう。
/etc/modprobe.d/nvidia.conf
options nvidia NVreg_MemoryPoolSize=4
