Hi Thorsten,

I am running Centos 5.2 compiled for 586 on a net5501.[root at centos ~]# uname -a
Linux centos.seclark.com 2.6.18-92.1.10.el5.soekris #1 SMP Fri Sep 12 14:33:06 EDT 2008 i586 i586 i386 GNU/Linux
[root at centos ~]# hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   756 MB in  2.00 seconds = 377.90 MB/sec
 Timing buffered disk reads:   76 MB in  3.07 seconds =  24.75 MB/sec

I am using a 4gb Transcend CF 266x TS4GCF266 about $40USD at newegg.com.

Steve
