Yup:

Driver `to-be-written' (should be inserted):
  Detects correctly:
  * Bus `SMBus I801 adapter at 5000'
    Busdriver `i2c-i801', I2C address 0x2d
    Chip `Fintek F75387SG/RG' (confidence: 7)

Driver `w83627hf' (should be inserted):
  Detects correctly:
  * ISA bus address 0x0290 (Busdriver `i2c-isa')
    Chip `Winbond W83627THF Super IO Sensors' (confidence: 9)

This is some kind of "high-density" PC, i.e. it is hard to disassemble.
I was lucky that the first chip was easy to spot, but the second one
could be anywhere. I would suggest to postpone this to tomorrow.

"Power control" reminds me of something: Sometimes ACPI power off
doesn't work. Do you think this is a related problem?

Creating a driver on my own sounds pretty cool. Probably it is
allowed to use an existing driver as a template?
