I ran into this exact same problem a few weeks ago, and unfortunately after a series of forums, IRC chats, and google coming up with nothing, it seems there is currently no way to change it from true to false. About the only concensus I've had ranges from recompiling the kernel with the KERNEL32.SetThreadPriorityBoost option set to true (which isn't even in the kernel config) or recompiling WINE with the same option set to true in the MAKE file (doesn't work either).
It might be a future option they plan on putting in later, but for now I think we're out of luck. Without instructions, there's simply no way to know how to do it without messing something up so bad that a reformat is required. I hope someone can help us out some day. Probably best to check back here every now and again to see if anyone figured it out.
