Pentium M with 533 MHz QPB and XD-bit is available for sale in Japan
While at CES 2005 notebooks vendors are only announcing notebooks on the new Sonoma platform, enterprising Japanese are already selling boxed versions of these CPUs.
These updated Pentium M are made using 0.09µm process technology (Dothan core), have 2 MB L2 cache and support 533 MHz QPB. New CPUs are likely to have a newer core stepping and we believe they actually support "Execute Disable Bit" (XD-bit) innovation to prevent some of malicious software by hardware means.
The new processors were packed into boxes just in the end of December. XD-bit support is indicated by the letter "J" before the sSpec#, which is unusual for Intel that traditionally places "J" on-box after the CPU model name.

Of all Pentium M chipsets existing in the market only i852GME unofficially supports 533 MHz QPB. Meanwhile XD-bit support is likely to arrive in Alviso series only.
Another novelty worth a mention is the new Celeron M also supporting XD-bit (and thus being based on the new-stepping core):
Other features of Celeron M 370 are typical for a 0.09µm core: 1 MB L2 cache, 400 MHz QPB. The clock rate is slightly increased to 1.5 GHz (vs. 1.4 GHz). sSpec# of this model is SL86J. The approx. price is $150.
It´s interesting that Pentium M and Celeron M seems to have cores of the same size (measured by eye):
