That may be a secondary error.  The first one may be in the VESA
driver.  Here's what I see in /mnt/var/log/Xorg.0.log:

[    84.601] (II) VESA(0): initializing int10

It seems that the VESA driver got an error and terminated.  The intel
driver was never tried.  Note that this is a BIOS boot, not an UEFI boot.

For comparison, here's part of /var/log/Xorg.0.log for the old BE:
