YEAH THAT! i've been wondering the same thing too. i really think it is the PS pump. i've been doing some research on the boards and people have said to flush out the whole system. i also was reading that a guy bought a new PS pump and still had the same problem, to fix his problem he has to completely bleed his PS pump by taking off one of the lines and the belt then hand turning everything so that the fluid levels would even out perfectly then the problem was gone for him.
this only happens on cold cold starts and i bet it's happening to a lot of people right now, including myself

There are alot of things that affect the power steering pump to make noise, could be air in the system, dirt in the system, needs power steering fluid, clogged system, etc...
First thing you do is flush the system. Never hurts to do this once in a while. Here's a guide to completely flush the system and bleed the system; http://www.lexls.com/tutorials/steering/psflush.html
While you're at it, check your ventilation hoses. There are only 2; 1 attaches to the intake and another to the manifold. If the hose is already hard and worn change it. It can really cause the PS pump to have hard time creating noise.
Since I changed my PS pump, rack and pinion and high pressure hose I haven't had this problem after bleeding the entire system. Although I changed to the driftmotion.com steel braided high pressure hose which completely deletes the 2 ventilation hoses, so my PS pump whines if I'm on an angled surface and my wheels are turned all the way. Not that loud though, nothing really that would bother me.

Sounds like your pump is going bad. Don you have any leaks from it ever before? Is there bubbles in your ps fluid? Is your fluid black? You can try changing your fluid, but guessing it's a 95 model or and 130 k new or rebuilt pump should do trick

When they are old to you and you know how Lexus put the *wonderful* variable power assist pressure valves on them, come back to the conversation.
