that team is fantastic!!
and early 2011 the Linux-Next Team (they had been developing amazing kernels for a long time!) had released completely new driver for Poulsbo chipsets. it called "PSB-GFX". the rock Alan Cox developed it. yeah he is god of opensourced Intel drivers... and also Kristoffer had managed Alan's codes to embed git development kernel tree.
So I had been contributing above codes to fit with Ubuntu-kernel as external "dkms". psb_gfx is the real KMS (Kernel Mode Setting) driver to handle framebuffer well. already we had some drivers for poulsbo, but all of them had not implement for such KMS features... for the future, I believe that we must need KMS features to run new born Graphical Window System, especially "Wayland". additionally psb_gfx had some great benefits to take us the higher by incredible 2D accel... :D this accel is similar to generic intel drivers, and also has "GEM" technologies instead of ttm or any other VRAM managements. for 2D rendering speed, it's the fastest driver in ours. today we could run this driver "out of the box" by employing 2.6.39 kernel.
this driver isn't perfect.
- because of some lack of dithering in fullscreen, it has ugly color gradations...
- acpi_video_register didn't match all of laptops.
so I've hacked the codes in above issues for Ubuntu... that's the reason why we had remained dkms in our PPA. dkms kernel system would give the more higher priority to external modules, so once you had installed our psb_gfx as dkms, you could avoid the default one safely... ;)
Anyway, this driver would be the baselines of poulsbo for the future... so I gotta fix some remained issues to keep up the support! :D
