Very interesting behavior. I've added this new line in /etc/rc.conf :
(until some minutes ago I didn't use it because I was using the intel
driver,installed by the package : xf86-video-intel-2.99.917.916_2,1)
kld_list="i915kms acpi_video"
and this line in /boot/loader.conf :
pptdevs="1/0/0 1/0/1 2/0/0 2/0/1 2/0/2 2/0/3 5/0/0"
and boom. pptdevs worked again:
# pciconf -l
ppt0@pci0:1:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1c02 subvendor=0x19da subdevice=0x2438
ppt1@pci0:1:0:1: class=0x040300 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x10f1 subvendor=0x19da subdevice=0x2438
ppt2@pci0:2:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1e04 subvendor=0x19da subdevice=0x2503
ppt3@pci0:2:0:1: class=0x040300 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x10f7 subvendor=0x19da subdevice=0x2503
ppt4@pci0:2:0:2: class=0x0c0330 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1ad6 subvendor=0x19da subdevice=0x2503
ppt5@pci0:2:0:3: class=0x0c8000 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1ad7 subvendor=0x19da subdevice=0x2503
So,maybe there is some incompatibility between the intel and the pptdevs
driver ? take also in consideration that on xorg.cong I'm still using the
intel driver :
Section "Device"
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
EndSection.
It's a confusing situation.
