Sony Vaio VGN-P and T2/Linux

Sony Vaio P

The Sony Vaio VGN-P is a very slim, lightweight and stylish, however "very expensive" sub-notebook that just weights about 620 grams.

Powered by the ULV (Ultra Low Volage) version of the Intel Atom (Z5xx) and new Pulsbo (US15W) chipset it even achieves over 3 hours of battery time with the standard battery, and up to about 8 hours with and optional, extended battery, despite the small size.

Notes

Suspend to RAM did not came back properly on a test machine - though it might with some VBE re-POST glue.

In a quick test the WWAN modem did not show up, although it is listed under "the other OS" as: Option Globetrotter GE40x (0x0af0, 0x7601). It might come up after fiddeling with: /sys/devices/platform/sony-acpi/wwanpower, ...

The machine lacks a digital video output (like DVI / HDMI) - the custom extension port with video out and ethernet only wires out VGA.

Accelerated video is not yet available in an open source form due ot the PowerVR based Intel GMA 500, Pulsbo, chipset.

It looks like the tested machine was an early prototype, the retail version appears to disable the VT of the Intel Z-series Atom in the BIOS, which might be possible to circumvent with some BIOS NVRAM value poking.
