Citez din man intel:

Please refer to xorg.conf(5) for general configuration details.  This section only covers configuration details specific to this driver.
The  Intel 8xx and 9xx families of integrated graphics chipsets have a unified memory architecture meaning that system memory is used as video RAM.  For the i810 and i815 family of chipsets, operating system support for allocating system memory is required in order to use this driver.  For the  830M  and  later, this is required in order for the driver to use more video RAM than has been pre-allocated at boot time by the BIOS.  This is usually achieved with an "agpgart" or "agp" kernel driver.  Linux, FreeBSD, OpenBSD, NetBSD, and Solaris have such kernel drivers available.

By default, the i810/i815 will use 8 MB of system memory for graphics if AGP allocable memory is < 128 MB, 16 MB if < 192 MB or 24 MB  if  higher.  Use  the VideoRam option to change the default value.

For the 830M and later, the driver will automatically size its memory allocation according to the features it will support.  Therefore, the VideoRam option, which in the past had been necessary to allow more than some small amount of memory to be allocated, is now ignored.

Ti-am spus, uita-te in log-ul X serverului ca sa vezi cat si-a alocat.

Deci, ca sa raspund direct la intrebarea ta, depinde de chipset, pt unul recent, nu poti tu sa aloci nimic, isi aloca el cat ii trebuie.
