Wine is a user level application, it's by definition a kernel/vidoe driver
bug if doing a simple video modes query (just once at start up!) makes X
block for several seconds.

Wine doesn't do anything of the listed below things as the reporter claims:

It talks about a bug in the Intel video driver.
