On which KMS is currently disabled in Debian Kernels:
,----
| linux-2.6 (2.6.32-21) unstable; urgency=high
|
| [ Ben Hutchings ]
| * [...]
| * [x86] i915: Blacklist i830, i845, i855 for KMS
| (Closes: #568207, #582105, #593432, #593507)
`----
And it looks to me as if Manu is using a newer version of
xserver-xorg-video-intel that actually requires KMS. The next upload of
linux-2.6 to unstable should re-enable KMS on the i8xx chipsets¹.
