I can also confirm on my ThinkPad T500 running Jaunty that the deb from
the PPA does not resolve stuttering in  flash video (e.g. fullscreen
Hulu, embedded YouTube), but the fixmtrr shell script does:

/proc/mtrr after installing the deb, before running fixmtrr.sh:
reg00: base=0x07d000000 ( 2000MB), size=   16MB, count=1: uncachable
reg01: base=0x07e000000 ( 2016MB), size=   32MB, count=1: uncachable
reg02: base=0x000000000 (    0MB), size= 2048MB, count=1: write-back
reg03: base=0x07ce00000 ( 1998MB), size=    2MB, count=1: uncachable

After running fixmtrr.sh:
reg00: base=0x07d000000 ( 2000MB), size=   16MB, count=1: uncachable
reg01: base=0x07e000000 ( 2016MB), size=   32MB, count=1: uncachable
reg02: base=0x000000000 (    0MB), size= 2048MB, count=1: write-back
reg03: base=0x07ce00000 ( 1998MB), size=    2MB, count=1: uncachable
