OK more weirdness. That new driver gave me IRQ conflict errors with my wireless card (bcm43xx: FATAL ERROR: BCM43xx_IRQ_XMIT_ERROR) and caused my computer not to be able to hibernate (got a message "OsSleep: Should not sleep this long in this context!").
BUT, I uninstalled it and installed the restricted driver from the repository and now it works again.

Very, very odd...
