[KMS] *ERROR* connectors have no modes

[rem5]

Hello,

I try to use KMS on a laptop with an X3100 (hp6720s)


and at boot I have this :

Apr 25 23:01:29 gentoo Linux agpgart interface v0.103
Apr 25 23:01:29 gentoo agpgart-intel 0000:00:00.0: Intel 965GME/GLE Chipset
Apr 25 23:01:29 gentoo agpgart-intel 0000:00:00.0: detected 7676K stolen memory
Apr 25 23:01:29 gentoo agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
Apr 25 23:01:29 gentoo [drm] Initialized drm 1.1.0 20060810
Apr 25 23:01:29 gentoo i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
Apr 25 23:01:29 gentoo i915 0000:00:02.0: setting latency timer to 64
Apr 25 23:01:29 gentoo [drm:drm_helper_initial_config] *ERROR* connectors have no modes, using standard modes

and after that no change : console stay with vga resolution... after X doesn't start (but possibly not related at all : more likely a problem w/ kde 4.2..)


I I boot without KMS no problem...


for info I use a gentoo (amd64 arch)

with the entire X stack from git and kernel 2.6.30-rc3


I found some report of the same problem (and even same laptop) on arch forum and redhat bugzilla but no more than report
