And even though the patches are mentioned... where can they be downloaded? (I've looked on the nvidia site and couldn't find the newer drivers either)

The patches in plaintext below. I didn't realize the SUSE list doesn't support attachments. -Mark Langsdorf Team Lead, Linux Device Drivers Advanced Micro Devices diff -u -u -r1.39 agpgart_be.c --- linux/drivers/char/agp/agpgart_be.c 2003/10/28 23:20:20 1.39 +++ linux/drivers/char/agp/agpgart_be.c 2003/10/28 23:26:02 @@ -67,6 +67,7 @@ EXPORT_SYMBOL(agp_backend_release); static void flush_cache(void); +static int agp_init_one(struct pci_dev *dev); static struct agp_bridge_data agp_bridge; static int agp_try_unsupported __initdata = 0; @@ -6490,15 +6491,24 @@ static int __init agp_find_supported_device(void) { struct pci_dev *dev = NULL; - u8 cap_ptr = 0x00; + int ret = -ENODEV; #ifdef CONFIG_AGP_HP_ZX1 if (hp_zx1_gart_init() == 0) return 0; #endif - if ((dev = pci_find_class(PCI_CLASS_BRIDGE_HOST << 8, NULL)) == NULL) - return -ENODEV; + while ((dev = pci_find_class(PCI_CLASS_BRIDGE_HOST << 8, dev)) != NULL) { + ret = agp_init_one(dev); + if (ret != -ENODEV) + break; + } + return ret; +} + +static int __init agp_init_one(struct pci_dev *dev) +{ + u8 cap_ptr = 0x00; agp_bridge.dev = dev; diff -u linux-work/arch/x86_64/kernel/mtrr.c-o linux-work/arch/x86_64/kernel/mtrr.c --- linux-work/arch/x86_64/kernel/mtrr.c-o 2002-09-05 17:27:05.000000000 +0200 +++ linux-work/arch/x86_64/kernel/mtrr.c 2004-01-16 18:27:04.000000000 +0100 @@ -70,6 +70,9 @@ #define MTRR_VERSION "2.02 (20020716)" +#define MTRR_BEG_BIT 12 +#define MTRR_END_BIT 7 + #undef Dprintk #define Dprintk(...) @@ -192,8 +195,9 @@ static void get_mtrr (unsigned int reg, u64 *base, u32 *size, mtrr_type * type) { - u32 mask_lo, mask_hi, base_lo, base_hi; - u64 newsize; + u32 count, tmp, mask_lo, mask_hi; + int i; + u32 base_lo, base_hi; rdmsr (MSR_MTRRphysMask(reg), mask_lo, mask_hi); if ((mask_lo & 0x800) == 0) { @@ -206,10 +210,16 @@ rdmsr (MSR_MTRRphysBase(reg), base_lo, base_hi); - /* Work out the shifted address mask. */ - newsize = (u64) mask_hi << 32 | (mask_lo & ~0x800); - newsize = ~newsize+1; - *size = (u32) newsize >> PAGE_SHIFT; + count = 0; + tmp = mask_lo >> MTRR_BEG_BIT; + for (i = MTRR_BEG_BIT; i <= 31; i++, tmp = tmp >> 1) + count = (count << (~tmp & 1)) | (~tmp & 1); + + tmp = mask_hi; + for (i = 0; i <= MTRR_END_BIT; i++, tmp = tmp >> 1) + count = (count << (~tmp & 1)) | (~tmp & 1); + + *size = (count+1); *base = base_hi << (32 - PAGE_SHIFT) | base_lo >> PAGE_SHIFT; *type = base_lo & 0xff; } @@ -243,7 +253,7 @@ base64 = (base << PAGE_SHIFT) & size_and_mask; wrmsr (MSR_MTRRphysBase(reg), base64 | type, base64 >> 32); - size64 = ~((size << PAGE_SHIFT) - 1); + size64 = ~(((u64)size << PAGE_SHIFT) - 1); size64 = size64 & size_and_mask; wrmsr (MSR_MTRRphysMask(reg), (u32) (size64 | 0x800), (u32) (size64 >> 32)); }
