You need KMS in kernel for Intel. Did you turn it on?

Have you tried booting with SystemRescueCd, if it works investigate how it does it.

OTOH, you mentioned you tried X -configure, not sure but methinks this command is not compatible with KMS. In fact, this command is obsolete and should not be used with any hardware configuration.
