Been working on this for hours but not getting much further :)
Logs doesn't show much:
while apmd is not running
i2c-amd756.o version 2.8.1 (20031005)
i2c-amd756: SMBREV = 0x3
i2c-amd756: AMD756_smba = 0xE4E0
and when running it just gives a:
i2c-amd756.o version 2.8.1 (20031005)
Have compared output and only the one from lspci differs
Output from lspci -xxx with apmd loaded

as i am not a coder i really can't use this for much other than i can
see the last line is different :)
The code from i2c-amd756.c:
};
static int __init i2c_amd756_init(void)
{
printk(KERN_INFO "i2c-amd756.o version %s (%s)\n", LM_VERSION, LM_DATE);
return pci_module_init(&amd756_driver);
}
static void __exit i2c_amd756_exit(void)
{
pci_unregister_driver(&amd756_driver);
release_region(amd756_ioport, SMB_IOSIZE);
}
And the code with modifications:
static int __init i2c_amd756_init(void)
{
struct pci_dev *dev;
const struct pci_device_id *id;
printk(KERN_INFO "i2c-amd756.o version %s (%s)\n", LM_VERSION, LM_DATE);
return pci_module_init(&amd756_driver);
pci_for_each_dev(dev) {
id = pci_match_device(amd756_ids, dev);
if(id)
if(amd756_probe(dev, id) >= 0)
return 0;
}
return -ENODEV;
}
static void __exit i2c_amd756_exit(void)
{
pci_unregister_driver(&amd756_driver);
release_region(amd756_ioport, SMB_IOSIZE);
}
