8 bits per pixel is not enough

As I just moved in my new apartment, I still have not all my machines, and thus it is about time to use the ones I use less than wanted because of role duplication.

In this case I'm speaking about laptops, and more specifically my PowerBook's (PowerBook3,4 and PowerBook6,8).

So, when I booted my "old" PowerBook (yeah, the G4 800 DVI - Ti) I felt somehow disgusted about the way the resolution looked in 8bit using the wsfb driver.
Nonetheless, as always, you can expect good documentation about nearly anything in the OpenBSD project, and thus, I found what I wanted in the dis tribution notes of the XF4 for macppc

Knowing my PowerBook had an ATI graphic card, this was so easy that I just had to follow what was explained in /usr/X11R6/README. Here is the relevant line in the dmesg about the graphics card:

vgafb0 at pci0 dev 16 function 0 "ATI Radeon Mobility M7 LW" rev 0x00, mmio
Now I wonder why I never took the time to do that when back in the days I used to use this laptop quite often. Lazyness I believe ;-)

Of course, this now brings us to another debate about the X Aperture and the security concerns around it.

Apple Sudden Motion Sensor

I just committed a work-in-progress on the Apple Sudden Motion Sensor (asms(4)) found in my PowerBook6,8:

asms0 at iic0 addr 0x58, rev 1.34, version 0.1
Currently, the sensors exposed via the sysctl(8) interface are:
hw.sensors.12=asms0, X_ACCEL, -1 raw
hw.sensors.13=asms0, Y_ACCEL, -1 raw
hw.sensors.14=asms0, Z_ACCEL, -57 raw

Some work is still needed but it's already in a usable state.
