Nope, this hack isn't even enabled in SVN Head; you need to
change a define and recompile. This is simply a hack to avoid
using an advertised feature of the drivers when that feature
is broken. This has to be fixed in the driver. The Intel driver
should be fairly easy to fix, if this isn't already fixed in
Xorg SVN, and the ATI driver won't be fixed unless people complain
to ATI. The intention of making it difficult to work around this
bug in the drivers is to encourage people who must use these
drivers to complain to ATI for the ATI drivers, or help the
Xorg developers test a fix for the Intel drivers.

The driver is advertising that it supports I420 surfaces when it
does not support them properly. Fixing the driver means either
removing this advertisement, or fixing the I420 support. Fixing
I420 support is just a matter of swapping the U and V pointers in
the XVideo surface, removing the advertisement of the feature is
a matter of commenting out one line in the driver.
