(Intel KMS) usplash crashed with SIGSEGV in memset_var()

[Robert Hooker]

Binary package hint: usplash

Usplash has never worked under KMS (I've been using it since january) when i915 is built into the kernel or loaded early from an initrd. It loads, displays the initial graphic then segfaults and further usplash events don't happen which is a problem when someone is using usplash and needs enter their crypt password. Perhaps splash should be disabled for intel cards for karmic since KMS is on by default? Or i915 could be removed from the initrd by the cryptsetup package? If there is any more info I can provide that would help, please let me know.
