It in fact depends on your definition of regression really :)

If we merge a buggy driver that hangs the user's machine when loaded, well 
... before the driver has been merged, the machine had been booting well, 
just some hardware was not functioning at all. After this late driver 
merge, the driver gets autoloaded upon boot and crashes the machine. Users 
will probably see this as a regression.

This doesn't mean that I am against merging new drivers as aggressively as 
possible, I just wanted to point out that it might bring actual 
regressions to users.
