When trying to run any GL application that renders something with r300g (e.g.

regression caused by the following commit:

radeon/winsys: increase the IB size for VM
Luckily, there is a kernel query, so use the size from that.
It currently returns 256KB. It can be increased in the kernel.

I am running Linux 4.1.6 (+ some Gentoo patches) and libdrm 2.4.64. The X.org
server version is 1.16.4 and the DDX driver is xf86-video-ati-7.5.0.
