自从在这台HP nx6330上装上了SuSE10.2，就一直没有享受过机器上自带的SD读卡器带来的便利，无他，不支持耳。今日小试牛刀，终于解决此问题，步骤如下：
1、以root身份登录系统；
2、运行lspci，下面是我本本上的结果：
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS/940GML and 945GT Express Memory Controller Hub (rev 03)

01:00.0 VGA compatible controller: ATI Technologies Inc M52 [ATI Mobility Radeon X1300]
02:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller
02:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)
02:06.3 Generic system peripheral [Class 0805]: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller

02:0e.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5788 Gigabit Ethernet (rev 03)
10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
请注意上面加粗和下划线的那行。
3、运行：setpci -s 02:06.2 4c.b=0x02。其中02:06.2来自于上面的结果。
4、插入一个SD卡，系统自动MOUNT到/media/xxx下。
问题解决，现在，我们来作个小脚本，让它每次启动后都能够自动识别该硬件。
cd /etc/init.d
touch sdcard
vi sdcard
#下面是sdcard内容
#!/bin/bash
setpci -s 02:06.2 4c.b=0x02
exit 0
chmod 755 sdcard
chkconfig -a sdcard
至此，重启系统后系统也能识别SD读卡器了。
