If I compile ia32 version of the OS, then (disregarding the fact, that userspace does not work), VESA/graphical kernel console is not visible. I can see output on the serial line and I can type in commands via the keyboard, but only garbage is seen on the screen.

If Frame buffer support is disabled (i.e. EGA text mode is forced), then the kernel console displays correctly. Without -M isapc, graphical console works correctly (i.e. with a system build for CPU=486).
