Hi,

First off, it works for me on my VAIO PCG-Z600NE.

Just a niggle however. This still isn't a very good test to finding a
Sony laptop. What'll happen on machines that have any sort of Sony
plugin device ?

How's about we test for a machine that has a host bridge with the Sony
subvendor ID, rather than any device.


WARNING!! untested code.

static int __init sonypi_init_module(void) {
    struct pci_dev *dev;

    if ((dev = pci_find_class(PCI_CLASS_BRIDGE_HOST << 8, NULL)) == NULL)
	return -ENODEV;		/* Bizzare. No host bridge */

    if (dev->subsystem_vendor != PCI_VENDOR_ID_SONY)
	return -ENODEV;         /* Not a Sony machine */

    return pci_module_init(&sonypi_driver);
}


I guess this'll still pickup Sony desktops.
Perhaps we need a survey of lspci -nv results for sony and non-sony
machines ?
