RedHat Linux 7.2 upgraded with:

XFree86 4.2.0, xfree86.org binaries, not the Rawhide's 4.2.99 (?) RPMs;

KDE 2.2.2-x Rawhide RPMs, qt>=2.3.1-5;

2 week old freetype 2.0.6-1, freetype-devel 2.0.6-1, in RPMs;

Bitstream Cyberbit Unicode font, regular .ttf installation routine (optional 
M$ Gothic, or Arial Unicode, plus MingLiU, plus Clearliu, plus GulimChe, plus 
Simhei, or Simsun families might be selectively denied AA -- by the "...edit 
antialias = false" statement, whatever your fancy. I prefer not to AA 
"sansserifed" ones of them, like Arial Unicode -- it's smooth and extremely 
well hinted when 'raw').

To actually see what the developers of XFree86/Qt/freetype/KDE have achieved 
so far, you would need some decent hardware:

Monitor with a bandwidth of 300 Mhz or more, pixel size/geometry of 0.22-0.25 
mm, capable of ~120 dpi or even better (usually Sony GDM-family, some 
Iiyamas, etc.), to really enjoy your kanji etc. Well, plain Latin typography 
looks like it was meant to, this is for non-CJK folks out there;

Video adapter with RAMDAC capable of 360 MHz bandwidth (like Matrox G400), to 
render these dots in 120 dpi very sharp, modeline ~1800x1440. 32 or more 
video RAM; probably no less than 384 Mbyte of system RAM for all those 
Unicode monsters with 29 to 50 thousand of glyphs.

...."now we're gettin' somewhere...."
My rig started to work as promised only yesterday, after 2-month long battle. 
Work continues on re-hinting, and partial (over 128) kerning of Bitstream 

Ask me for details.

AU -- Sorry for the 8th bit
