No you should not need WHQL for Windows 7 64bit. You need a
valid signing certificate but not WHQL. WHQL driver package
will have no warnings. Non-WHQL but signed driver packages
will generate a warning about publisher but will not get
rejected.

The QXL driver appears to have a valid digital signing certificates
and valid timestamp but I have not verfied it myself (not using spice
myself). You can use WDK's signtool to verify the certificate.
