XTestFakeButtonEvent with buttons > 3?

[McDonald, Michael-p7438c]

We've been using XTestFakeButtonEvent quite happily to inject button
events until a user decided to use the scroll wheel.

	Major opcode: 147 (XTEST)
	Minor opcode: 2 (X_XTestFakeInput)
	Value: 5

So I take it that Xtest only supports buttons 1 thru 3. Has this been
fixed in newer versions? (We're using version 1.0.1-3.1 from RH5.3)
