so far as I've read, there are no digitals without dead pixels... the
pricier
the camera, the fewer of these you should expect. Ive also read that
chips are sold... among manufacturers... somewhat like diamonds...
they are inspected, the best are sold to the pricey brand names, the
imperfects are sold to the el-cheapo brands... the chips ready for the
trash bin are sold to... well... I wont mention names here ?
In all seriousness, I dont think it's possible to mass produce a chip
without -any- defective pixels.
The good news is... since, as you state, the bad pixels always show
up in the same spot... you can prepare a mask and manually process
these spots away.
This is the advice I got after boldly announcing my used HP was
picking up dozens of "uncharted stars" in night photos :--)

Many cameras have the ability to map out bad pixels, automatically
interpolating the missing value from adjacent pixels.

Hmmm. My dead spots are blue.

Well that's disappointing. I had a $300 Fujifilm that eventually got
a few dead pixels after about three years, but to have dead pixels in
an $800 camera a month after taking it out of the box, I just wonder
if I'll wind up with many dead pixels before long.

Interesting. I don't recall that in the D40x manual, so that's
probably not a feature for me.
