Mmm, this one is present in the -pseries kernel :

  CONFIG_FB_MATROX_G=3Dy

So i guess you had only problem with this with Cajus's kernel ?=20

what is the config option for this one ?=20

Huh, i suppose this is the one :

  CONFIG_SCSI_IPR :
  This driver supports the IBM Power Linux family RAID adapters.
  This includes IBM pSeries 5712, 5703, 5709, and 570A, as well
  as IBM iSeries 5702, 5703, 5709, and 570A.

Well, this is built as module, as it should, but maybe it is not included=
 in
the .udebs. ...

Indeed it is here :

$ find /lib/modules/2.6.11-pseries/ -name ipr.ko
/lib/modules/2.6.11-pseries/kernel/drivers/scsi/ipr.ko

Will do a new .udeb build tomorrow to include them, can you provide me wi=
th
the lspci and lspci -n output of those devices to check that discover kno=
ws
about them ?

How do you built that .deb ?=20
