由kernel 2.4.27 升級到 2.6.8後不能使用網路卡

[cfw8521]

我的環境是 Debain 3.1 sarge main ，想架設 DRBL 的環境
原來的 kernel2.4.27 ( vmlinuz-2.4.27-2-386 ) 可以上網可是使用 kernel2.6.8( vmlinuz-2.6.8-2-686-smp )後卻不能上網。
是不是因為雙cpu的關係呢?
在板上找了一些相關資料，確定核心有抓到網卡、pppoe等，不過就是不能使用網路卡。
還請各位大大們幫忙檢查一下，謝謝

想請教幾個問題，
1．在 kernel 2.4.27下時我的網卡IRQ是佔用了17
可是在 kernel 2.6.8 時卻沒有佔用irq，我要如何在kernel 2.6.8 下設定我的irq呢?而網卡的io設定是在二種核心下是一樣的。
2．在 kernel 2.4.27下時發現 via-rhine 的模組好像會使用到 mii 和 crc32 這二個模組，請問這是作什麼用的?
在 kernel2.6.8 下我只找到 mii 模組 ，不過我有將 libcrc32c crc_ccitt 這二個模組加入。
3．如果我irq設定好了之後需要重開機嗎?要如何查證我的irq有設定正確呢?是 cat /proc/interrupts 內容嗎?
已經在BIOS下將PNP 關掉了，不過造成了USB找不到IRQ，還是不能在 kernel 2.6.8下使用網路
