The great Cyrus64 posted this news over at http://www.boob.co.uk :

This enables the use of pvr texture dma in KallistiOS 1.1.8 for copying data (continuously) from system ram to vram. It is the first time the use of pvr dma has been available in homebrew software. By default any calls to pvr_txr_load will instead use pvr texture dma as opposed to store queues.
YUV420 dma support can also be added simply, and with some rearranging within kos, dma could also be used for sending display lists to the pvr2.
It should be added to the kos cvs soon.
