The jogdial driver would be one such customer, a driver for this brightness futzing would be another. Alternatively, /dev/spic could simply be a low level interface with sort of read register / write register ioctls being available from user space. All of that is basically waiting on suitably stable ACPI support. Right now the spic driver has ugly pci access hacks to map itself into memory. By rights, it should simply use ACPI to configure itself automagically. Anyhow, I put -stable on my Vaio because ACPI wasn't ready yet. If anyone can confirm that they have ACPI working on a Z505 series Vaio, I might come back. :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
