backported kernel [2.6.35] 'enable_mtrr_cleanup' boot option broken

[Alex Sytnik]

1) OS Ubuntu 10.04.1 LTS
2) faulting package name 'linux-image-2.6.35-22-generic', version '2.6.35-22.34~lucid1'
3) Hardware 'Aces AspireONE 150'.

Due to hardware specific issues to solve MTRR allocation problem 'enable_mtrr_cleanup' boot option was provided (as described here https://help.ubuntu.com/community/AspireOneDiscussion), which work fine with previous kernel 'linux-image-2.6.32-22-generic' version '2.6.32-22.36'.
With 2.6.32-22-generic kernel and 'enable_mtrr_cleanup' boot option MTRR table looks like:
reg00: base=0x000000000 ( 0MB), size= 1024MB, count=1: write-back
reg01: base=0x03f500000 ( 1013MB), size= 1MB, count=1: uncachable
reg02: base=0x03f600000 ( 1014MB), size= 2MB, count=1: uncachable
reg03: base=0x03f800000 ( 1016MB), size= 8MB, count=1: uncachable
reg04: base=0x040000000 ( 1024MB), size= 256MB, count=1: write-combining

After installation of new backported kernel (linux-image-2.6.35-22-generic) MTRR table becomes:
reg00: base=0x0fffe0000 ( 4095MB), size= 128KB, count=1: write-protect
reg01: base=0x0fffc0000 ( 4095MB), size= 128KB, count=1: uncachable
reg02: base=0x000000000 ( 0MB), size= 512MB, count=1: write-back
reg03: base=0x020000000 ( 512MB), size= 512MB, count=1: write-back
reg04: base=0x03f800000 ( 1016MB), size= 8MB, count=1: uncachable
reg05: base=0x03f600000 ( 1014MB), size= 2MB, count=1: uncachable
reg06: base=0x03f500000 ( 1013MB), size= 1MB, count=1: uncachable
reg07: base=0x000000000 ( 0MB), size= 128KB, count=1: uncachable

which exactly the same as previous kernel did without 'enable_mtrr_cleanup' boot option.

In attachment is output of 'dmesg' command.
