Well speaking as someone whose older card worked fine under 9 and now 
just ends up as a black screen with both the intel driver and the 
modesetting one on 10.0. I'm more interesting in getting back to having 
a working accelerated X setup. I did see the tearing on the intel driver 
on 9.x but it was never bad enough to make me try the modesetting driver.

For reference my now broken hardware is:
[     1.008474] pci1: i/o space, memory space enabled, rd/line, wr/inv ok
[     1.008474] i915drmkms0 at pci0 dev 2 function 0: Intel Haswell 
Integrated Graphics Device (rev. 0x06)

See kern/57268 for how my hardware fails.
