Let's just be clear:
For laptop 1 with Intel graphics card:
- syscons + text mode: resumes ok
- syscons + X: resumes ok?
- vt: blank screen
- vt + i915kms + text mode: resumes ok
- vt + X: resumes ok?
For laptop 2 with ATI graphics card:
- syscons + text mode: resumes ok
- syscons + X: resumes ok?
- vt + text mode: blank screen
- vt + X: ???
For ATI, there is a radeonkms driver I believe. Can you try loading that when
you are using vt(4) to see if it makes a difference?
