Just tried a kernel with serial console, sti console, and sti fb all
compiled in, with palo/unstable. Seems to do the right thing on my B180 :)
The kernel knows it cannot support b180 fb, so uses sti console automatically
but this kernel should use sti fb on those machines that we support.
I left the b180 alone until the "screen blanking" cut in. It just turns
off the cursor, btw, doesn't blank the screen.
When I came back to it the cursor had gone back to top-left, and all
chars are printed as blobs of garbage. System is still happy apart from
that.
I think the cursor going to top-left on a screen blank is a result of
your last lot of bug fixes, but not certain of that.
The other thing for people to note is that if you specify both
console=ttyS0 and console=tty0, then the order is important. The
real console is the second one you specify, the other just gets
a copy of boot messages (all kernel printk's, I guess).
