There is a bug in the R128 driver in XFree86 4.2.0 which causes a 
hang due to DMA being used with Xv.  The XFree86 in Null/rawhide 
has contained a fix for this for a while now.

Different cards use different drivers.

If Mandrake XFree86 contains a bug fix for something which ours 
does not, I am more than happy to investigate it, and add it to 
our XFree86 if it is sane.

What specific version of XFree86 are you using?

    rpm -q XFree86
