You're jumping to conclusions here - before you can mount a harddrive (or
rather, a filesystem on it, not that g4u would do that!), you have to
detect both the drive and the controller on which the drive is, plus
maybe even the bus on which the controller is.
My guess is that the SATA controller is not found/recognized for some
reason.

That's not the information on the harddisk. wpi(4) is about your wlan
adapter (which requires seperate firmware to be installed, which g4u
doesn't offer; and which it probably can't, thanks to the binary-only
availability), ubt(4) is some bluetooth module as you can see.
What we would be looking for indeed is something like a drive which would
most likely be something like wd0, which would be attached to some
IDE/SATA controller (the name most likely has an 'ide' in it, even for
SATA), plus again what bus that controller is attached to.
Here's an example for the relevant parts of my PC:
viaide0 at pci0 dev 7 function 1
viaide0: VIA Technologies VT82C596A (Apollo Pro) ATA66 controller
viaide0: bus-master DMA support present
viaide0: primary channel configured to compatibility mode
viaide0: primary channel interrupting at irq 14
atabus0 at viaide0 channel 0
viaide0: secondary channel configured to compatibility mode
viaide0: secondary channel interrupting at irq 15
atabus1 at viaide0 channel 1
...
atapibus0 at atabus0: 2 targets
...
wd0 at atabus0 drive 0: <ST320413A>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 19092 MB, 38792 cyl, 16 head, 63 sec, 512 bytes/sect x 39102336
sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(viaide0:0:0): using PIO mode 4, Ultra-DMA mode 4 (Ultra/66) (using
DMA)
>From this we can see information about the drive (wd0), the controller
(viaide0) and the bus (pci0).
My guess is that the whole PCI bus on which your controller is isn't
found right now.
