The pci_device_id tables in linux-2.4.7-pre3/drivers/char/sonypi.c
claims that the driver wants to be loaded on all computers that have
an that have a PCI device with vendor id PCI_VENDOR_ID_INTEL and
a device ID of either PCI_DEVICE_ID_INTEL_82371AB_3 (0x7110) or
PCI_DEVICE_ID_INTEL_82801BA_10 (0x244c). My Kapok 1100m notebook
computer has an Intel 82371ab, so the sonypi module automatically
loads at boot time and hangs the computer.
sonypi_init_module needs to do some kind of test to figure out
if it is on a Sony Vaio and abort otherwise. Looking at the result of
"lspci -v" on my Sony Vaio Picturebook, I see that, while none of the
PCI devices have Sony's vendor ID, a number of them have Sony's
vendor ID as their subsystem vendor ID's. So, I have implemented the
following test to cause sonypi only to be loadable on machines that
have at least one PCI device that has a subsystem vendor ID of
PCI_VENDOR_ID_SONY.
