Description changed by baremetal:

Old description:

The intel HD graphics output is broken on a Celeron N2930 (Bay Trail-M)
processor while using haiku its intel extreme drivers, vesa mode works
flawlessly. Haiku was booted from USB on a medion akoya E7226 notebook.

intel_gart.cpp hardware id:
{0x0f00, 0x0f31, INTEL_MODEL_VLVM, "ValleyView Mobile"}

Haiku beta: boots to vesa mode
Haiku hrev53938: broken driver

New description:

 **Update:**
 Beta 2 and hrev54319 do not suffer from the same corrupted screen output.
 Both boot to a normal and performant framebuffer mode. There are syslog
 and screenshot attachments for both.

 Currently only tested with: UEFI booting
