Hi Rudolf

> Please can you get some more information about the DRAM used?
> If it is some DDR2 or whatever.

The memory I'm using is:
PC1600R-20330		0446
HYMD264G726 B4M-H
512MB DDR 200MHZ ECC REG


> Also please can you do
> i2cdump 0 0x50

[root@ ~]# i2cdump 0 0x50
No size specified (using byte-data access)
WARNING! This program can confuse your I2C bus, cause data loss and
worse!
I will probe file /dev/i2c-0, address 0x50, mode byte
Continue? [Y/n]

btw, I also test it on linux-2.4, with the same result as linux-2.6:
#sensors
eeprom-i2c-0-50
Adapter: SMBus ALi 1563 Adapter @ 5000
Unknown EEPROM type (0)

Thanks
