Frankly, I don't know. Borgert reported problems in his first mail:
a) In `vi' (elvis-tiny) the first five lines are always
garbled, also sometimes in `less' etc.
b) Worse, the xserver-svga seems to have problems when
switching from the uncommon 30x80 to graphics mode,
when you have an ET4000/W32P chip. This is already
documented in README.Tseng or so.
and we now know the first (a) is a problem related to elvis-tiny,
and nvi is not affected by frame buffer mode.
The solution for the second problem may have two options:
b-1) use xserver-fbdev in place of xserver-svga
I don't know the difference in performance on a specific hardware, though.
b-2) use boot time option "video=vc:8" with xserver-svga
This will disable frame buffer console on vc1-7 (tty1-tty7) and may work,
but I have not tested it yet.
The frame buffer console is not provided vanilla kernel on i386.
And the other arch where frame buffer console is widely used
does not require the extra warning, so we may not require the change
in scripts/rescue/messages.
I would rather suggest the change in documentation/en/rescue-boot.sgml:

But we may have to check this "video=vc:8" can work with xserver-svga
before this modification. I will wait the report from Bronson and Borgert.

Sorry, it was my fault to specify 3-5. (I thought it did work, but when
I checked it again, you are right, vc:3-5 does not work. I was wrong.)
Can you check if the vc:7 or vc:8 can work with X (xserver-svga or else) ?
I think vc:7 will needs xserver-fbdev, because the /etc/inittab in base2_2.tgz
have the entries for tty1-tty6 on the default run level 2, so the console
which is used by X server will be tty7.
From the same reason, I think vc:8 won't need xserver-fbdev, and can work
with xserver-svga or so.
Regards.
