2.4.0-t4-vmpatch rocks

[Rares Marian <rmarian@linuxstart.com>]

Just a note: this has to go into the official release.  I'll have more to say later today, but i'll leave with these two anecdotes:

1. 2.4.0-test4 caused synaesthesia-xmms to perform very poorly.

The patch fixed it.  The comparison is striking.  Not: rebuild modules, my sb32awe modules failed after the patch, so I had to rebuild them.

2. I used blackbox because mozilla and netscape performance as well as interactions with gnome drove me insane but I need 2.4.0-test4 for my TV input card

Normally, it would take between 30 and 45 seconds under 2.2.15 and 2.4.0-test4 unpatched to just start Helix.   While in blackbox I decided to test the patch.  I was able to shut down X, desktopcfg to GNOME, and get Helix 1.2 Preview + themes + several panel applets up in not more than 30 o seconds or so.  It's at least 2-3x faster.

It's up to Linus if he wants it in.  If it doesn't go in the official release I'll hack it in myself.  And I'm not all that experienced.

Note: Rik van Riel released the vmpatch a couple days ago plus a 1 line correction.  People can find the full patch here.

This was on an Athlon 500 w/ 64MB RAM UltraDMA66 20G IDE drive Gigabyte (hdparm 3.9 fails :/ though in boot up Mdk 7.0 says it's ok.)

Thanks to Free Unices, we've crawled back UP to 70's.
