VESA mode on VMWare doesn't show a command prompt until you hit ENTER

Description

When I try to boot in VESA mode on VMWare, I get a console that looks like it is not working. The screen looks like the attached image. When I hit ENTER, the VESA console jump scrolls to the end of the buffer and I see a command prompt.

The issue is that the console should come up with the input cursor at the end of the buffer, and I should see the bootstrap messages scrolling to the console ... without me needing to hit ENTER.

This is my original issue description ...

When I try to boot in VESA mode on VMWare, I don't get a working console. Instead, I get a pretty looking screen with the first page full of console messages; see the attached image. When I configure the serial port and boot with kdb, the kernel debug output doesn't contain anything that points to the problem.

It might be a problem in refreshing the screen.
What happens if you press enter?

Magic! It works. I'll update the title and issue description to say that VESA-mode console needs to do something to cause the screen to refresh.

I tried it in kvm today and with "-vga std" VESA works.
startawt works without the refresh trick (I have to do some more testing but I have the feeling that this is dependent on the kvm version, I tried kvm-83)

On Thinkpad X60 the vesa mode didn't work at all btw as the grub version (0.97 too) does not understand the vbeset command for some reason.

And on another note: the software cursor is broken, too. If you move the cursor to the upper border you get garbage.

what's your hardware ? does it support VESA ?
if you have a stacktrace, it could help Eye-wink
