odd scrolling issue in vim

[Jack Howarth]

   Has anyone else noticed this issue under Fedora 9 x86_64
with the 2.6.25.10 or 2.6.26 kernels? I find that if I open
a large text file in vim (as vi), jump to the bottom of the
file and then use the 'k' metakey to scroll up that the scrolling
is not smooth like in earlier Fedora releases. There is a huge
lag in the process of scrolling up. Oddly scrolling down the file
seems to be pretty smooth. This bug is really annoying. I assume
it must be a vim bug.
