without knowing what OS you're using it's difficult to say exactly what's going on. is the profile properly set up in windows color management? have you tried running the LUT loader after it reverts back? assuming you're using vista, have you tried setting a schedule in task scheduler to run the LUT loader a few seconds after login?
are you doing design and/or photography work with your X300's internal display using color-managed apps or are you simply trying to remove perceptive color cast for general use? if it's the latter then the gamut controls in the intel video control panel may be markedly easier. besides, let's not kid ourselves here, "near-professional" will be difficult to achieve on a 6-bit, 45%-gamut, 250:1-contrast-ratio notebook display.

i had a hunch you were using vista.
LUT = look-up table. it's the table used by your video card driver to determine how each color has to render. by changing values in this table, each color can be made brighter, darker, or shifted in hue.
the way i worked around the vista issue is to set a schedule in task scheduler to run the LUT loader roughly 15~20 seconds after login. this covers both login after boot and after recovery from sleep. it's a PITA but is the only workaround i can think to do.
i briefly glanced over the article you've linked above and it sounds like exactly what i went through back in august when i received my T61p and first used vista. i'm still using vista today and have since decided to live with the added headache with vista's color management interface (or lack thereof).
if all you need to do is remove color cast then seriously consider using the gamma controls in the "color correction" section of the intel GMA control panel. if your display appears too blue then just knock the brightness down on the blue channel until it looks good to you. since you aren't doing design work with the X300, this will be a perfectly viable solution.
