register dump with working tty1 screen

I have a motherboard Asus P5VD2-MX SE with P4M890 and integrated VGA output.
Lubuntu 16.04. Dell S2740L FullHD monitor connected to VGA output.

I noticed that with newest drivers I can't see anything on the screen after
switching to text console with Ctrl+Alt+F1. Returning to X session (Alt+F7)
works normally.

I bisected commits and found this one as the first with problem:

    Rewriting iga1_crtc_restore

    Rewrote iga1_crtc_restore callback function, in order to improve
    ACPI S3 State resume reliability.

Driver with version before this commit shows TTY1 normally.

Attached register dumps from normal and problematic versions (blindly logined
and run "via_regs_dump -d -m -p").
Xorg.0.log files also are attached.
