Thanks for taking the time on this.

I am unsure of the "specific IndiLinx firmware build number" though I've
noticed the release numbers are common for different manufacturers.
For example my disk came with the then-latest firmware "1819"
(with TRIM) which had write-perf issues then they recently released
"1916" which added TRIM and GC support (seems to work very well
I should say).

Linux logs "CRUCIAL_CT128M225" and "1916" in my dmesg, speaking
of which, here is my latest full dmesg: http://pastebin.ubuntu.com/363659/

And here is the output of hdparm --Istdout /dev/sd? :

I am running the following on Kubuntu development version, uname -a is:
"Linux thunderbird 2.6.32-11-generic #16~vishalrao2 SMP Tue Jan 26

The " ~vishalrao2 " portion indicating it being the proposed patch -
in that good old "works for me" kind of way.
