Well, I asked on #debian and someone answered that it is possible to use 133 MHz SDRAM mem units in a 100 MHz bus. It also seems so according to: http://en.wikipedia.org/wiki/DDR_SDRAM <<< There is no architectural difference between DDR SDRAM designed for different clock frequencies, e.g. PC-1600 (designed to run at 100 MHz) and PC-2100 (designed to run at 133 MHz). The number simply designates the speed that the chip is guaranteed to run at. Hence you can run DDR SDRAM at lower clock speeds than it was made for (underclocking) or higher clock speeds than it was made for (overclocking). Note that overclocking should only be done by those that know what they are doing (see overclocking for details on why). >>> So, I think we can safely buy some new (or used) 133 MHz units, and get done with it. The maximum memory allowed by this model is 1 GB. If we want to use the maximum capacity (which I recommend), then we either need four 256 MB units or two 512 MB units.
