No more AT24C1024B?

I just got an obsolete part notice from Digi-Key on the AT24C1024B, the 128 kbyte 1 MHz IIC EEPROM. Their suggested replacement for it is the 400 KHz Microchip part. And also isn't the Microchip part the one that can't be linearly addressed out to 512K with four chips? This seriously crimps a plan I've been working on for a year and a half. Anybody know what's up with this and if there are other options?

You can stack them next to the pile of Walmart eReaders you (and I) are hoarding.
It turns out that it is a process upgrade and the pin and function equivalent 1M part will be the AT24CM01

It does look like they are dropping the DIP8 and DFN package, but the new part# will be available in soic and tssop.
Change Description:
Atmel has optimized the layout of the 1-Mbit AT24C1024B Industrial Temperature Grade Serial EEPROM. The catalog part number AT24C1024B will be replaced by AT24CM01 (see Table 1). The new devices are pin-to-pin and functionally backward compatible with the current AT24C1024B devices with the following exception and enhancement.
In order to increase manufacturing flexibility and to ensure a long-term continuity of supply, Atmel will manufacture all package options using both gold (Au) and copper bond (Cu) wires. Atmel reserves the right to ship devices with either gold or copper bond wires.
